Has nothing to do with their closed eco system. They basically did similar stuff with some of the stuff in the sm3d collection thingy.
Nintendo is a company that only wants make new stuff, innovations.
For example, they ( mostly miyomoto ) has been quoted to not understand that people want another f-zero, as the game’s principals and ideas have been fully flushed out and no new ideas could make it feel like something new.
They also usually dont do remakes/remasters unless its so new/different it can be considered a new game ( see metroid 2 on 3ds ).
If that is a smart business position to have, i will leave for you to decide, but do get your facts a bit straight :)
EDIT: also, nintendo has used open source projects for internal projects before, so idk how “closed ecosystem” is part of their stuff :)
Just for your information : belgium is allowing the balcony solar panels this year, but they have put limits on which you can install. The power supplier needs to have approved the kit you install. This is just to prevent people from getting cheap crap from the internet.
Other than that, same rules!
