I would guess it's not just Comcast. Optimum serves my area and they've basically been begging people to switch back since this area got fiber a few years ago.
Their offers are like $25/mo for 200/10 Mbps and no data caps. But they're not guaranteeing the price. Seems like they're going after the lower end of the market.
I basically say "boo hoo". This is what actual competition looks like. Cable companies have sat on their ass and milked their infrastructure for decades (only updating the headend equipment to keep up).
Optimum cold called me once and I flat out told them if they wanted me back, they need to run fiber to my home, give me the same symmetrical speed I have now, for at least $10 less than I'm paying my fiber provider, and lock that price for at least 5 years. The rep basically kinda sighed, so I guess they've heard that response from more than just me.

I can understand that speeds vary by area, but it's not like it's difficult at all to have those in a database where a web tool can return them based on your zip code. But yeah, it was like that when I signed up with Optimum (nee Suddenlink) years ago.
The other thing they do is require a truck roll for any kind of hookup. They almost got some of my business back but were so rigid that I said "the hell with it". My fiber provider was having some growing pains and I called Optimum to reactivate my service on a lower plan to use as a backup connection (I work from home). All they needed to do was setup the account and re-authorize my modem (my hookup was still live and I had my own modem). They flat out refused to do any of that and required a tech to come "within 3-5 business days" and read the modem serial number to them to activate it. So I said hell with it, called T-Mobile, and activated my old 5G hotspot.
