Incorrect, Raymond Hill authored both extensions, both being forks of HTTP Switchboard.
Raymond got overwhelmed with managing an open source project of uBlock's size and let Chris Aljoudi take over. Adblock later purchased it from Chris.
Meanwhile, Raymond had forked uBlock, creating uBO, and continued to improve it on his own terms. After seeing what happened with Adblock, he has no intention of selling either uMatrix or uBO.

You're right, let me try to amend my statement: at the point uBlock Origin was forked, Raymond disowned the earlier uBlock, and it had become unrelated to him, hence "not the same author" (even if it was started by him). My point was that Raymond didn't want to become involved in the pay-per-ads-let-through scheme the commenter I was replying to mentioned.
I love uMatrix, but all evidence is that they stopped developing it in 2021.

I don't know the implications of that, it's the only tool I've ever found that lets me feel in control of what programs my browser is executing.
