It’s perfectly fine to sell your software. There’s trillions of dollars worth of companies that do that.
But I make sure I eat through other methods so I’m able to donate my time.
If Elastic doesn’t want Amazon to use their software, then they shouldn’t release it as OSS. It’s quite simple.
But it’s ridiculous, I think, to claim Amazon is doing anything wrong by abiding by the license.
Elastic shouldn’t feel that Amazon is eating their pie because they chose to put their pie out with a “free pie for everyone” under ASL. If they feel bad, that may be so, but their feelings aren’t as important as what their intellect should set up.
