Really an honest question. I find Docker useful, and was put back also by the email/ login request, but why are they getting so much hate, compared to every other company, just because of this?
Docker is "revolutionising infrastructure" or something. It doesn't have "make heaps of money" as it's primary goal. Partly this is because open source. There's an expectation that open source is also "for the greater good".
The cardinal sin of our times is hypocrisy. Being a money-worshiping greedy capitalist bastard is fine, as long as you're open that that's what you are. Pretending to be altruistic while actually being greedy will generate all the hate.
Would you spend time out of your day to contribute to software that requires your users to sign up for someone else’s spam list?
Yeah...
The "open" in "open source" is about encouraging cooperation and collaboration. And not using lock-in or patents or walled gardens to obstruct competition.
If the altruistic aspect is still not obvious: many projects encourage a gift economy by accepting donations.
Astroturfing is really not compatible with what you called "be transparent about the product design/intentions"
However, the kind of mindset that enjoys being a greedy capitalist bastard finds it very very hard to accept the Open Source philosophy - it's all fear-based, "do unto others before they do unto you" and so "if they can rip my code off, they will", because that's what they'd do. I've experienced way too many hard conversations about open-sourcing code with this type of person.
So there tends to be a correlation between Open Source software and a co-operative mindset that would find this type of coercive marketing bullshit to be evil and reject it. This correlation becomes an expectation.
This was a bad marketing-driven move, but that's all it is.
