TV viewership of SFV Evo finals decreased this year

There's no doubt fighting game event Evo is a big one among the Fighting Game Community (FGC), but it turns out that Street Fighter V's TV ratings for the finals of the competition on EPSN2 show a decline from last year, as reported by PVP Live.

The finals brought in an average of 180,000 across three hours, around 136,900 of those being in the 18-49 bracket, whereas last year saw 201,000 viewers on average, although it should be said that this year's broadcast was roughly the same as Twitch numbers, which match last year's roughly.

Regardless, do you think this decrease is something to be worried about? Why do you think it's dropped?
