I just use FOSS. I don’t trust that proprietary garbage. I generally don’t pirate software in general. Its far too easy to trojanize it. I also buy games on steam to support linux/deck and valves investment in the ecosystem, I buy them steeply discounted though. With Roms, sales and free games I have a massive backlog so being patient pays off.
I also find that the quality of the FOSS stuff is better and way more configurable. Not hating on anyone that does pirate software or prefers proprietary stuff, to each their own
