If you think that Google or Microsoft are Evil Corporations, you haven't really seen Evil.
Meet Larry Ellison, who is almost 80 and somehow still alive. Larry heads Oracle Corporation since founding it. Every single product that Oracle has ever bought was either killed or turned to shit.
Oracle bought MySQL (mostly to kill it), which in turn resulted in MariaDB fork. In 2023, I can say I haven't seen MySQL/MariaDB used for quite a while for anything except PixelFed (for some reason) and Amarok (yes, the music player).
Oracle bought Sun Microsystems and KILLED EVERYTHING SUN HAD EVER MADE WITH FIRE with the sole exception of Java. SPARC? Dead. Solaris? On life support. In fact, Solaris was open source/free software/whatever you wish to call it before the acquisition. After the acquisition, no Solaris code was ever published again.
Let's talk about the main product of Oracle Corporation, the Oracle Database Management System. Did you know that Oracle explicitly prohibits publishing any benchmark results without prior approval? That's right, if you own a licensed copy of Oracle DBMS, you can't tell anyone how good it is. Because if you do, your license will likely be revoked and you might even get a fat lawsuit. So far, this is the one of the two databases I know of with the license having this clause. IBM has a similar thing in their DB2, but only to an extent. IBM DB2 license requires that all published benchmarks must provide full information for reproducing the results, including hardware specs, OS settings, et cetera. MSSQL is the other DBMS with a license clause prohibiting sharing benchmark results without their prior approval, but this is Microsoft we're talking about.
The feud between benchmarks and Oracle goes back to the early 80s. In 1983, Dr. David DeWitt benchmarked Oracle DBMS and published results, which made Larry furious. To the extent that Larry wanted DeWitt fired from the university where he worked. Rumour has it, for years after that DeWitt couldn't land jobs because many companies were afraid to lose Oracle licenses for hiring him. Imagine being that petty.
Anyhow, I'm glad Oracle doesn't own any product I use or I am forced to use. I hope Oracle dies from cancer filled with cancer, yes, the entire company. They deserve it.
