Yep, I feel like they are giving their userbase over to matsavant, who in turn will likely step up their game given all the recent interest and traffic. The timing just seems odd here given they finally have a "competitor", but likely it wasn't based on that. I'm guessing it was more of a "ok, we can't keep doing this for free anymore" and not some long term financial windfall business plan. At the end of the day they are wrestling junkies with a tech background who made a wonderful thing, I hope they find success.
The market has spoken and it agrees with you 100%, I'll pay for WS if matsavant is lacking, like you I didn't even know about it so I haven't had to the time to suss it out yet. But I know I'm an anomaly and most won't.
