I keep hearing the take that GoG sells you games, and Steam sells you licenses.
This is not the case.
They both sell you licenses. The only real difference between the two is that GoG's installer can be burned to a CD and work offline, so they can't physically remove your license - Though they absolutely can remove it, in which case you're legally obligated to destroy your copy of the software.
Whether you do or not is your own prerogative, but saying they're all that different is a bad take.
Literally, the difference between GoG and Steam is one has an offline installer. (Yes there is other differences. Yes, Steam offers a DRM solution. No, Steam does not require developers to use it. Yes, steam has DRM Free games on it. Yes, you can just copy those game folders, and even make your own GoG like installer.)
