I think we need to get back to state where we take software licenses serious in letter and in spirit. The transitions Redis made are pristine on a legal and moral level. Feeling betrayed is absolutely uncalled for.
Not sure why Redis is blamed for the "rug pull". They didn't relicense the old versions. They just said "sorry guys, we don't want to support this project under those terms anymore". They are under no obligation to do that, legal or moral. Don't like it? No problem, fork it and maintain it yourself (as many did). But don't demand of others to continue to support the project under those terms if they do not want to. This is FOSS working as intended.
All those people that contributed, did so to the FOSS version. Their contributions live on in all the forks, both FOSS and proprietary (by Amazon & co., and Redis before today). So not sure where "betrayal" supposedly happened. Maybe when Amazon used their contributions too?
They already had made a strong statement by choosing BSD when GPL was at their disposal. That is a much stronger statement than some blog post that reflects a momentary snapshot of their plans.
It is just that people don't hear what they don't want to hear. Every BSD or MIT is a loud and clear statement to deny the guarantee that derivative works will remain free and open.
Because Redis said they would never do something and then changed their mind (which makes the whole concept of saying you will never do something useless), while Amazon never said they wouldn’t use open source software for free (which is their right).
