Why is 2019 the final Bronycon?

I'm not a traveler so I've never been to one, it really means little to me as a convention. But as a fan of Friendship is Magic it seems like a sign the fandom is willing to let it dwindle and that's a shame. I've seen numerous shows and comics fandoms dwindle to almost nothing since the 90s and it's extremely disappointing.

the old Transformers convention Botcon popped up in 1994. It's true Generation 2 was ongoing after American Transformers had ended by 90 or 91 but it was failing rapidly. The comic was cancelled after only 12 issues and the cartoon was just re-edits of the 80s cartoon
