Hopefully you won’t mind me using their own arguments to promote this OSS web analytics project instead:

https://counterscale.dev/

Unlike Simple Analytics (the post authors), you deploy Counterscale to your own Cloudflare account and control the code + data end-to-end. It also uses no cookies, has no browser fingerprinting, and has no monetized SaaS offering.

It only has 90 days retention though, which could be viewed positively.

I am all for the hustle. Startups are difficult. So, even though I don't like the post, I understand it is done because it works.

It's simple fear mongering and aimed at the wrong audience. Companies want people tracked to improve their ads and have a higher reach. The people who are being tracked can't exactly do much about what tracking system a website uses.
