There is a certain degree of trust involved in using a product like Docker since it is so critical to a businesses' operations, and I think a lot of people feel like using any kind of tracking (like mandatory registration to download) erodes that trust - we're forced to sit here and wonder what other restrictions might come in the future, or what other information they might start requiring for use of their product... and uncertainty never pairs well with infrastructure tooling that tends to be very important and very longlived within an organization.
It's not about entitlement, but it is about common convention. Docker's offering isn't unique enough for them to betray that convention.
The point of making something open source is to benefit from collaboration. Is not making the argument, "locking software distributions behind a login wall is harmful," simply a form of collaboration?
whether i agree with the decision or not, i am confused by this sentiment. aren’t they offering docker, for free?
