Yeah, it’d be great if everything was open source and everyone was happy.
But that’s not really what happens. Redis and Elastic are popular exactly because there’s entire companies behind it constantly maintaining it, securing it, and adding features.
If you want use open source software at your job that’s a hard requirement. No, you can’t use “MySillyKeyValueCache” that Timmy develops in his free time with no security or compatibility concerns.
Companies cost money to run. Google and AWS exploit open source work for profit, and don’t contribute back enough to ensure its support. This is what you should be really mad about. The internet giants are literally killing open source.
If they have their way you’ll be stuck with their proprietary software. In practice AWS is already there.
