I've been designing electronics and firmware professionally for my entire career. Right now I'm acting as a consultant developing a network-enabled industrial device. It's going to be powered by an Arduino simply because it's easy to do, robust enough (after I design appropriate power supply protection), and most important: enormous amounts of documentation and experience in the community means I can probably complete the entire project in less than a day of work.
That's what matters. Not some mistaken concept of "gentrification" because you're pissed off at opening up your Good ol' boys club.
