I think the downvote is a well deserved punishment for the pointless denigration of Mozzila. I use Chrome at home and was using Firefox at work untill very recently. I had to switch to Edge at work. I also use Internet Explorer (for sites of previsou century). Firefox is around the same level as Chrome on almost everything. Edge is a notch below. Denigration is a poison that hurts a lot.
I agree the tone of the parent comment could use a little work, but think it's a valid point - I'm not sure it can count as denigration if it's something they've actually done.
In terms of "put up or shut up" I should make clear I'm not advocating Mozilla shut up, more that they put up next time something like DRM in browsers is on the table (which they ordinarily do, which is why I use their browser).
I never denigrated Firefox as a product. It still performs adequately for many users and the source code model is a bit more friendly to FOSS distributions compared to Chrome. I called Mozilla an irrelevant vendor due to their disconnected leadership, diminished browser marketshare and now-fractured community, that makes all such shouty blogposts seem desperate.
