I used this bike for CX racing. My LBS would replace the BB at the end of each season, along with pretty much every other bearing on the bike, as part of a post-season overhaul.

I don't consider replacing a worn out bottom bracket to be an issue, but I'm curious... do threaded BB's last longer than PF BB's?

That is the issue with the press fit. It needs to be replaced. It costs time and money. That is just one reason why they suck. A threaded bottom bracket does not not need to be replaced every year. Or hardly ever.
Press Fit BBs do tend to keep the bike shop people busy and keeps that $$$ flowing for the shop and that is the main reason why the industry loves them.

have you seen the conditions that cyclocross racers ride in? I'm surprised that some of those folks get a set of bottom bracket bearings to last a month, and that has nothing to do with how the bearing is fitted into the frame. CX racers with ANY bottom bracket interface are likely to replace their bearings with some frequency due to the abuse that riding in sand, snow, ice, water, mud, etc. puts on the bearings. replacing a press-fit BB is no more time consuming and requires the same number of specialty tools as a threaded BB, so bike shops/ the industry are not benefiting in that regard. anyone can do that job at home and the replacement bearings for a BB30 cost about the same as a comparative threaded BB but with fewer wasted parts.
I'm not saying that either is "better," just that your reasons for not liking press-fit bearings don't hold water.

I have no issues and have not seen much comment on the FaceBook Topstone page as to this being an issue.

Yikes. Every year? Wow. That is a serious issue.

Interesting take. I've never heard someone make the claim that threaded BB's last longer.
My CX race bikes are overhauled at the end of every race season. The type of bottom bracket doesn't matter, it gets replaced as part of the overhaul regardless of threaded vs pressfit. The shop doesn't charge me extra for this, it's part of the overhaul package. I'm sure many people go much longer between pressfit BB replacement. Like anything, this is highly dependent on mileage and conditions.
