I don’t think this will work. If companies can get away of slapping us by doing “please use Google Chrome or other Chromium-based browsers” just because Google implements the most niche, probably privacy-last, feature ever, then they will get away with it this time, again.
It’s like Reddit, as an link aggregator (Wikipedia said “social news aggregation […] website”), but federated (in the Fediverse), as in it is not centralized and built upon many instances of Lemmy, not just one centralized website like Reddit.
