Corporations steal from us all the time, and they don’t even let us buy their content, they only sell limited access that can be revoked at any time (see https://lemmy.dbzer0.com/post/9531016 or https://lemmy.dbzer0.com/post/12904663). Under these circumstances, there are no ethical issues with piracy.
I highly recommend the Prism Launcher. You can find it in the standard Linux Mint Software Manager.
