I've been thinking about how many ways Comcast has fucked over customers in the past few years
The jump to fully digital meant digital converter boxes became required to have any access to any channel. Originally these were free but also of trash quality that frequently had issues or didn't work at all. After a "grace period", they started charging $2 per box. It's now up to $5. Not only that, any channel that is offered only in HD is not available on the regular boxes, you have to get an HD converter box, which is $7-10. Want to watch the sports channels you pay for out in the garage or basement? Gotta pay an extra $10 per TV.
"Basic cable" is $20ish a month. What used to be essentially channels 1-60 or so is now local channels and QVC/CSPAN/religious networks only. Yes, Comcast charges you $20 a month to have access to local stations that are free OTA.
They automatically upgraded internet speeds, which meant you had to upgrade your modem, which is more expensive than the previous ones.
They push their Xfinity Stream app and browser versions heavily, right after they instituted data caps in areas they didn't used to enforce, so now people are going over caps watching Comcast's own platform that they push on you so they can get people to go over the caps for penalty fees. The X1 platform also accesses the internet for all of its UI, and I believe some VOD is internet instead of cable based, adding more to your data usage.
They regularly "miscalculate" your bill. It's the only company you have to check every line of your bill every month because they absolutely add false charges. 30 cents here and there, taxes don't add up, and suddenly your bill has gone up $20 over a few months with no services added. I have no idea how they aren't frequently sued for this. I assume they bank on people not actually looking at their bills and that seems to be true. I'd say I've had to contact them about charges that don't add up or make sense every 2-3 months for 5-6 years.
In my area at least, there have been regular outages for years, sometimes lasting up to 48 hours. Usually it's just a few hours, but sometimes it's longer. Of course, you're never compensated on your bill for the time you had no access, never even get a letter apologizing for outages once in a while. This happens about every 2 weeks, never late at night or anything, but at like 2 in the afternoon.
On their internet streaming, they're still using Flash. In 2018.
