Apparently you like to read. Open the EULA for basically any commercial software (not FOSS or open source, costs money, isn’t made by some small company, basically the same criteria as >90% of the games on Steam) and you are going to learn 2 things very quickly. First, all of them are just a license to use, and second, if there are patches or an online component you will have at least as many caveats and restrictions as what is included in the Steam TOS.
Now, I’m not saying you’re wrong or that I’m okay with this situation (I look for open source, free, then paid for all the software that lets me do whatever it is I’m trying to do), but the situation with Steam is very typical.
