I know I read articles about that (much like the right to repair articles with respect to CAT heavy machinery), was there any legal action against any of the printer companies you know about? If I recall the outcome correctly I believe the printer companies lost the fight, but I don't know/remember if that was voluntary or court ordered.

As it relates to printers/cartridges unlike my car manufacture/gas hypothetical or the app store, I could potentially see certain IP (from patents to trade dress) rights that may actually help the printer companies argument (but again I think they backed down anyway).
