Nobody doubts that TX are a legitimate group. Indeed, I had an Xecuter 2 CE for my Xbox back in the day. Nor do people doubt that they’ll support their device in the medium term.
The point is that closed projects don’t contribute much to the scene in the long term. They provide quick fixes for people, but none of their developments can be expanded upon by other developers. Instead, people are at the whim of what TX chooses to do, similar to how people were in that situation with Gateway until open solutions helped the scene grow. I don’t really want to start an open source vs. closed source debate here, but closed source doesn’t actually make much sense in a scene like this where most of the developments are made by individual developers rather than companies.
Open vs closed source has been a debate forever on any form of software, we can't stigmatize TX for going with the latter, I believe that competition drives progress, everybody is free to adopt the strategy they prefer, even in piracy imo.
