Because software has this weird status where you increasingly don't own a perpetual use right to the copy of the code you bought, and can have it revoked for reasons that have nothing to do with the purchase agreement. What if one day in the not too distant the electrical system on your car stopped working because an auto software update from that vendor (not the company that sold you the car perhaps) detected your name was on a DB of no-service-updates, and there was a critical big patched?
For a tangible example, imagine saying something pro-HK on an online multiplayer and losing access to your entire library of Xbox games.
From Microsoft's community guidelines:
"Under permanent suspension, the owner of the suspended profile forfeits all licenses for games and other content, Gold membership time, and Microsoft account balances."
And in 2019, saying things as asinine as "haha I banged ur mom" are enough to trigger such a suspension, despite the embracement of such an immature, tongue-in-cheek culture being tantamount to Microsoft's early success in the gaming industry.
Or see yesterday's executive order putting sanctions on subset of Venezuelan population, followed by Adobe suspending accounts of everyone in that country. Think of entire occupations affected by this. What if tomorrow the tools for your job disappeared because some people on the other side of the world have a disagreement with your government?
