Maybe I'm missing something here...
From the business side of things, I really don't understand why the label would buy Lasers. Now I'm not saying a label would never do this (maybe they will try to boost sales to build hype for a new artist, or for whatever other reason), but under these circumstances, it just doesn't make sense for them to do so.
From what I understand, Lupe only has one album left on his contract, and it's pretty clear he's not going to resign with them. Whether Lasers flopped or did well, their relationship is so fractured it is highly doubtful that he is going to resign with them. And if they did want him to resign, why put him in the position of power by inflating his numbers. I think everyone can agree that this is his worst album to date, but if he can still put up big numbers like that, it just shows what kind of following he has, and that in and of itself puts him in a very strong bargaining position if they were ever to go back to the negotiating table.
So what does the label gain by posting big numbers? Profits from sales. But if they buy their own albums (at retail rates) they would be buying at a loss. They are still a business and I am having difficulties believing that they would make this kind of investment just to say "I told you so" to an artist that they are soon to have no influence over.
