Idk, I don't doubt that they know what they talk about.
However, some counterpoints:
- We already have working esp mods although they shouldn't be possible at this point. Are they risky to use? Sure, but the ones I use work for me.
- Modding for Starfield before official mod support already feels on a whole different level than it was for previous games.
- Bethesda built Starfield with modding in mind more than any of their previous games. I doubt they did anything to cripple the modding capabilities. Big changes always happened from game to game. There wouldn't be any progress without those.
They are scammers and nobody should feel sorry for them.
I bet even this was planned from the beginning. Get some money out of the "game" and then just disappear.
