companies will no longer publish the source code for their projects
100%
Whereas, before a company may contribute something they created for internal use and they may have put something to try and stop direct competitors from using it (like restrictions only for cloud providers) now they probably will just not publish at all.
Im not a big fan of fake open source, but source available is better than closed source.
To be fair, some of the "fake open source" was a result of some projects seeing their projects taken by a cloud provider, charging for it and not contributing ANYTHING back to the original project. Can't really say I blame them.
