It's many times been the case that the most adaptable succeed the most, that living within a rigid, preconceived notion of how things "should be" and being unable or unwilling to adapt would just result in hardship for oneself. I never went in as a Founder thinking that PGI must do 'x', 'y', and 'z' because that is exactly what they stated they would or wouldn't do, I went in as a Founder because I really loved Battletech as a kid and wanted a less twitchy mech sim. I didn't care if there were a few minor things that would marginally affect a battle's outcome (coolant flush, P2W, whatever you perceive) because I knew I wouldn't be playing at the top echelon, I just wanted something fun. I didn't care if it was 1PV or 3PV, but I loved the 1PV "look" so I tossed a few coins PGI's way. Now that they've added a 3PV option over a year later in order to entice a larger player base at trying out their game, and therefore keep this game and the franchise floating longer, I don't have a problem with that, too.
My preconceived expectations are not the sole framework by which I judge their decisions, the hours of enjoyment I've garnered per dollar spent
are. If 3PV ends up souring my experience, the game as a whole for me, and it just sucks...well, as an adult with a job and expendable income I'll move on to any of the dozens of other really, really good games out there to spend my money on. So far from the reports coming, it changes the game a little but isn't nuanced so strongly that it breaks the entire game in half for the average player.
And I'm fine with that.
TL;DR version : quitcherbitchin', grow up, vote with your dollars and not with your mouth, adapt or die or get out
