This, I should think, is Lynn's way of constantly trying to justify her baffling decision to drop out of school to marry her first husband and thus inconvenience the parents who paid for it and expected her to do something useful with her degree. My personal guess is that she sort of thought that they were trying to dictate to her when, in fact, they were trying to get an entitled, oblivious and immature twit to keep her eye on the ball. Since she thinks that anyone who offers even the mildest form of criticism is a bully who wants to boss her around because they haaaaaaaaaaate her and want to see her suffer, we have to deal with nonsense like Gavin charging his son rent because he wanted to get paid for temp work.
That being said, it's not as if this meed to shudder in horror at the prospect of becoming what Beth and Lynn misinterpret as their being nothing more than a pawn in a game that a heartless old man wants to play doesn't provide us with a lot of fun. Not only do we get to remind ourselves that Tony Soprano looks like the picture of generosity stacked up next to John and Elly Patterson, we can recall with some fondness the reason why Rhetta's being "forced" to "surrender her identity" and "enslave herself to her parents' whims" is extra-ludicrous. The reason that she was "bad" for Mike was that she wanted to stay in Milborough and keep him from travelling the world. Since Mike's ambition was to fort himself up in the attic of the Pattermanse so he could achieve the writer's trance, that seems a stupid thing to hold against her.
