Actually you have to click past a "please donate some money" nagging dialogue.
It may be a little annoying (at least if you download ISOs all the time), but it's obvious what they are asking for, not to mention why.
And it's definitely not dishonest, so it doesn't tarnish their reputation as a trust-worthy company.
We are talking the price of a hipster coffee per fortnight here, but a few thousand people putting that on a recurring payment adds up.
For organisations like Docker I'm wondering if the RStudio model would be viable? The 'enterprise' subscription is something like $995 a year and can thus be budgeted for &c.
I also sometimes buy apps even if I'm not really sure I'll keep using them (sometimes just to encourage them to continue),
and keep subscribing to a newspaper even if I don't often read subscriber only content (since they sometimes have some great investigations && I want to support them but don't want to disable Adblock).
What I don't do:
- most monthly subscriptions that isn't payment for an actual service .
If I download an Ubuntu Server ISO, I get my download immediately, but the page has a nice prompt to register for a whitepaper to get the most out of my new server product.
If I download the Ubuntu Desktop ISO, I still get my download immediately, but additionally I see some nice prompts about donating to support their operations.
Everything about both flows inspires trust that they aren't trying to withhold my download for the sake of selling consulting services or soliciting donations.
