Comcast would be quite unhappy with me as I'm arguing against monopolies, and for consumer choice.

Consider two companies, A and B.

A offers capless at e.g. $50/mo, and B offers capped at $40/mo.

Now B can no longer offer capped, and they have to raise prices to $55 to invest in better networking. A is cheaper, and pushes B out of the market. Now A is alone, and due to it's monopoly position raises prices to $60.

End result: Your capless connection now costs $10/mo more, and some people even end up paying $20/mo more for internet.

Yay?

Reducing competition helps the ISPs, not consumers, yet somehow I'm the shill?

I reiterate what I've written elsewhere: protect consumers by forcing companies to add choice, instead of forcing them to remove it.
