Honestly, I can feel sympathy for the OP.
Mind you, not everyone is actively seeking new MMO around. Perhaps he just discovered Mechwarrior Online too late, like I almost did. Plenty of people are yet to discover this game - that's all we can hope for - and none of them will ever be able to purchase a founder package. Mockery, snarling comments and victory dance are certainly not warranted for.
Sure, Piranha Games could just allow founder packages again, but it would make early adopters angry, for good reasons. For a game still in Beta stage, it would not bode well to alienate the diehard Battletech fans allowing this game to exist in the first place. Some already complained founders pack availability lasted too long.
On the other hand, Piranha Games and Mechwarrior Online need to grow and earn more. It would be stupid for the company to turn away potential customers by telling them "hey, welcome, but incredible deals are a thing of the past". Despite all groans and moans from established player, special deals and extra offers for new players are almost guaranteed - and, considering the situation with detachment, some may even look better than now-unavailable founder packages.
We just have to wait to see how they get implemented. Be patient and be faithful!
But for the forum Founder icon it's probably toast.
