[2022] Why in the world does Sealed not count toward Limited Rankee?

In order to contribute to rank, an event needs to pair by rank. (Don't want to give someone in Diamond progress for beating someone in Bronze, nor take pips away from someone in Bronze for losing to a Diamond.)

If an event pairs by rank, it changes the benefit for high skill. In a ranked event, high skill means you're playing in a higher rank bracket, which means more skilled opponents and more complex, interesting games. In an unranked event higher skill translates straightforwardly into a higher winrate. Unranked events are also a better match for the tabletop experience.

Different players prefer one experience over the other, so where we can we provide both (ranked & traditional drafts, ranked & play in constructed). Sealed play volumes aren't high enough to do this (especially with Bo3 Sealed), so we have to pick one. In this case we chose unranked because that makes Sealed a better match to a traditional pre-release, and it works well for the somewhat more casual audience Sealed gets.

Aha! Someone caught the mistake that I, um, clearly inserted into that answer very deliberately. Yes. (I think the general point still stands: rank gains & losses only really make sense when being measured against others of the same rank)
