Valkey Celebrates Its First Stable Release As Open-Source Redis Fork

[Nth_man]

All of those big corporations run modified versions. They share changes they like to share and keep private what they don't want their competitors to have. The BSD license allows that, the GPL doesn't. They leech off your OpenSource project, you are giving them free stuff if you do BSD.
And those same corporations then brag about supporting OpenSource when they let something trickle down.

The decision between MIT/BSD and GPL is (mainly) if you want closed source projects to be able to use your code (and compete against your software) without giving back.

(In practice it's more complicated with license incompatibility and so on.)
