They recently changed it so you'd get a PR the first time you rode a segment. They took a lot of heat for that. I'm wondering if they reverted back to the previous system.

Personally I pay very little attention to KOMs (which I never get) and PRs and such, I mostly use Strava to track mileage and to see what my friends are up to, but I can see why getting PRs the first time on a segment would bother someone.
