Icarus It's fine with me if MCAS is a system designed to prevent excessive AoA, which could result in stalls, just like I don't have a problem with the Airbus alpha floor protection. If MCAS activates to prevent reaching an AoA higher than the safe limit, it sounds like a nice feature to have. Of course, assuming MCAS was designed properly with the adequate redundancy in its inputs.
My main problem is the insistence of some people that the purpose of MCAS is just to adjust the stick feel, and it isn't related at all to stall prevention. That may be the case, but Boeing seems to have nevertheless implemented a system that focuses on limiting AoA rather than just adjusting stick feel. So, whatever their original intent was, it seems they actually implemented a stall prevention system.
