Mlb just loves chasing away it’s fans.
I don't think this was MLB, on the XM side the NFL has been on All Access forever since the merger, and MLB was on the All Access on the Sirius side. By moving MLB (and possibly NFL in the future) they have two major sports on their premium product. I wouldn't be suprised if they continue moving play-by-play sports over if they have success in upgrading people.
I enjoy MLB on radio, and have in the past used the audio in the MLB app or had MLB.TV which included the audio. Last year I just used the XM app instead. I usually carried All access in the fall/winter for NFL games anyway (for if we're driving on a Sunday), so now I"ll likely just carry it all year.
Instead of calling every six months for their $30 deal at $5/month plus royalty, now I'll end up calling every six months for their $50 all access deal at $8.33/month plus royalty. Like clock work, every six months, it's on the calendar. At least they've gotten faster on the discount conversation, and it doesn't take 3 offers to get to that number anymore. Though last year I got the same pricing for 12 months instead of 6 months which was nice.
