Lexmark did more than that. They chipped even their printer display panels so you couldn't pull a perfectly good one out of a new printer and swap it into yours.
Went through this exact thing and went rogue swapping the prom chip over from my old board to the new one to get it to work. Lexmark wanted almost half as much (at retail, no other source for new with no BS attached) for their display panel module as the whole printer cost! Screw Lexmark.
I can't tell you what current generation printer models are doing, but in my experience, Brother is less tight fisted about sneaky ways to lock down their hardware and carts.
However, I should add... you need the details for the specific model you are considering. My brother B&W laser, the starter cart needed a new higher capacity reset gear while the full cap retail carts don't, but after that point, I just dump bulk toner into it until the drum is worn out then get a new retail brother cart for the new drum, then repeat the process of bulk toner refilling it till the drum wears out again.
It also depends a bit on how much you print, how important this is. I used to print a lot more than I do now, so it was a cost per page issue while now I look at it more as cost per year, whether the printer takes decent sized carts or some ridiculously small ones trying to make their profit on cart sales.
I also rotate two carts. One, is bulk refilled a few times, and there is some toner "snow" on the pages, not much so it is perfectly acceptable for my needs but I also have a original-fill retail cart I can swap in if I need the best print quality possible... which I seldom do, but I have it as a backup too in case I get that low toner message and need to keep printing till I decide whether to bulk refill again or get another retail cart.
