Aren't most players who group doing so with their guilds and/or friends? I certainly don't think you can conflate the number of entries in a group finder with "the amount of people interested in group content on the whole PCEU".
Also, Endless Archive launched today so I dare say a lot of players are trying that out, and it can't be done in a group. I suspect that will turn out to be a 7 day wonder, however, so you may find an increase in grouping and the use of the group finder before long.

Of course, I may be wrong.
