this is not exactly the case; itch.io does separate games, not mods, and that's what's locked behind a paywall. As for Patreon, its a donation-ware service, not intended to be used for primary payment; sadly, several games have taken it this way. Still both itch.io and the aforementioned Bethseda games like Fallout/Skyrim, include content that is still free, much of which is far and away better than what is paid for. Also Sims 4 afaik does not support "Paid Mods", they just release a lot of dlc which is...regrettable, but unavoidable in today's market.
