Sunk cost is a helluva drug
Worst case scenario, a few years from now: "centralized/curating" clients continue to grow in MAU, investment and noise. There are still n or greater appreciators of the purely decentralized nostr vision, with n being far smaller than it could have been were it not for noise/money/attention being lopsided towards the centralizing/curating.
There's probably nothing to be done about this once the balance starts to shift thanks to lopsided investment. The good news is that us n users will get to enjoy our experience forever, centralizers be damned. The bad news is for any future users who may have noticed and joined the n group, had they not been crowded out by (the market's preference for) the alternative.
