That's "over the air". The channel 2 PBS progs are on (WGBH; 2 stations) but the channel 44 progs (WGBX; 3 stations) are not.
I care about "Sunday Morning", which last-I-checked is not available on the internet, & drama progs which are. But everybody on the WBZ (CBS) website wants to watch, uh, a football game. This Afternoon.
Website says cable is OK, but various smaller-cable viewers are saying back on the comments section "no we're not".
Since OTA is out, satellite is of course out too.
CBS & PBS share a place on the broadcast antenna, which is why they are both out together. Not the 1st time this has happenned. Some of the times took a long time to fix.
