@absurdoldbird - I'm aware that this is a free service (at the base level, anyway - I pay for some features) and I accept the related restrictions as such.
However, this is a different animal: WP set up the themes and then promoted them with the features (at the time) so that members could make an informed choice about those themes. Having done so, WP cannot unilaterally change them. It is different from the layout of hidden statistics and such. There is a legal principle known as fettering one's discretion, but I won't bore readers with the details.
I don't agree with you that we do not get to have our say. You certainly have been having your say on this and other related threads, as have I and others. This is one issue of many and WP has, in my experience, been responsive. And, we don't yet know what the outcome will be, so your comment is, at the very least, premature.
On the whole, WP does a great job. In this instance, they did not. Time will tell whether they address the problem properly. However, I think our time is better spent focusing on the issue (infinite scrolling) than engaging in ad hominem attacks on WP.
