hey cofounder here. since it takes my 16 year old neighbors son 15 mins and $100 claude code credits to hack your open source project

Right, but those capabilities are available to you as well. Granted the remediation effort will take longer but...you're going to do that for any existing issues _anyway_ right?

I understand why this is a tempting thing to do in a "STOP THE PRESSES" manner where you take a breather and fix any existing issues that snuck through. I don't yet understand why when you reach steady-state, you wouldn't rely on the same tooling in a proactive manner to prevent issues from being shipped.

And if you say "yeah, that's obv the plan," well then I don't understand what going closed-source _now_ actually accomplishes with the horses already out of the barn.

Give him $100 to obtain that capability.

Give each open source project maintainer $100.

Or internalize the cost if they all decide the hassle of maintaining an open source project is not worth it any more.

I'm not aiming this reply at you specific, but it's the general dynamic of this crisis. The real answer is for the foundational model providers to give this money. But instead, at least one seems to care more about acquiring critical open source companies.

We should openly talk about this - the existing open source model is being killed by LLMs, and there is no clear replacement.

Are you at all worried that the message you are spreading here is "We are no longer confident in our own ability to secure your data?"

I don't think this really helps that much. Your neighbor could ask an LLM to decompile your binaries, and then run security analysis on the results.

If the tool correctly says you've got security issues, trying to hide them won't work. You still have the security issues and someone is going to find them.

Re:Cal.com is going closed source by evanelias on Wednesday April 15, 2026 @02:54PM (#47783542)
If I understand correctly, their primary product is SaaS, and their non-DIY self-host edition is an enterprise product. So your neighbor wouldn't have access to the binaries to begin with.
Re:Cal.com is going closed source by wild_egg on Wednesday April 15, 2026 @11:50AM (#47780831)
It only takes 20 minutes and $200 to hack a closed source one too though. LLMs are ludicrously good at using reverse engineering tools and having source available to inspect just makes it slightly more convenient.
Re:Cal.com is going closed source by keeda on Wednesday April 15, 2026 @02:13PM (#47782990)
Very true, but that is still a meaningfully higher cost at scale. If, as people are postulating post-Mythos, security comes down to which side spends more tokens, it is a valid strategy to impose asymmetric costs on the attacker.
Re:Cal.com is going closed source by NetMageSCW on Thursday April 16, 2026 @03:14PM (#47798132)
A little harder when you don’t have the source or the binaries.
Re:Cal.com is going closed source by sambaumann on Wednesday April 15, 2026 @11:45AM (#47780747)
Couldn't you just spend those $100 on claude code credits yourself and make sure you're not shipping insecure software? Security by obscurity is not the correct model (IMO)
Re:Cal.com is going closed source by bayindirh on Wednesday April 15, 2026 @11:55AM (#47780937)
Why not can’t you (as in Cal.com) spend that amount of money and find vulnerabilities yourself?

You can keep the untested branch closed if you want to go with “cathedral” model, even.

What makes you think it'll take him more than 16 mins and $110 claude code credits to hack your closed source project?
Re:Cal.com is going closed source by NetMageSCW on Thursday April 16, 2026 @03:15PM (#47798141)
SaaS makes that harder.
Re:Cal.com is going closed source by pdntspa on Wednesday April 15, 2026 @11:51AM (#47780859)
whooptie fuggin doo, then spend $200 on finding and fixing the issues before you push your commits to the cloud

To what end? You can just look at the code. It's right there. You don't need to "hack" anything.

If you want to "hack on it", you're welcome to do so.

Would you like to take a look at some of my open-source projects your neighbour's kid might like to hack on?

Is that true? Didn't the Mythos release say they spent $20k? I'm also skeptical of Anthropic here doing essentially what amounts to "vague posting" in an attempt scare everyone and drive up their value before IPO.

No it doesn't. Have you been actually "hacked"?
Re:Cal.com is going closed source by Maken on Thursday April 16, 2026 @05:43AM (#47790807)
Was open source any more secure before LLMs became so cheap? For those same 100$ you could have a North Korean hacking your code for a whole month.
