You couldn’t be more out of touch with reality.

Ok, name one building block type piece of software that isn't open source and is a market leader.

I meant you’re wrong about Redis. It was in a unique position for a long time, if you pulled it out there would be nothing to really replace it.

RedisLabs does charge for redis (extensions, and support) and seems to be doing pretty damn well for the matter.

You haven't really said where I was wrong.

Charging for extras is not the same thing as charging for the product.

Ok, and why do you think most people use Redis? Is it (1) they did a careful evaluation of the options and selected Redis because it was best or (2) everyone knows you use Redis if you need an in memory cache?

Wasn’t the case until at least 2016. Memcache was the default.
