Talking about bait and switch for Redis makes no sense.
Redis is a 15 years old project started in 2009 by Salvatore 'Antirez' Sanfilippo. He worked on his startup, then at VMWare, them at Pivotal, and only joined Redis Labs (created in 2011) in 2015.
In 2018 Redis Labs changed the license of their modules and Antirez published http://antirez.com/news/120 In 2020 he quit.
Anyway I agree with the conclusion: Redis will be forked, the fork will win and Redis Labs will become irrelevant.
I'm curious about something: I suppose Salvatore still owns the copyright for most of the code? The old license does include his copyright, up to 2020: https://github.com/redis/redis/blob/7.2/COPYING So I think this change couldn't have been done without his explicit consent? Or did he transferred his rights to RedisLabs or a foundation?
What your link points to is the BSD license, so yes, he owns the copyright but also gave everyone permission to use and modify the code as they see fit.
There is nothing that prevents anyone to use this code in combination with proprietary code and sell the resulting project for money. If he didn't want that he would have chosen a different license.
