Yes, but it should be making MARC trains stop more often with new EMU rolling stock. None of this map works without having fully electric transits without the stop/acceleration penalties of stops with these frequencies. Of course, the NEC is already electrified and for some time MARC did use electric locomotives, but our idiot transit agencies swapped to diesel and are continuing to invest in diesel.

That said, I’m not sure I’d want the frequency of stops on local trains on the purple line. Certainly that’d be the last priority— I think it’s more important to use EMUs to get an easy, at minimum, 30 min ride to DC consistently leaving at :00 and :30 at least 12 hours a day.

FWIW, $60 for internet is pretty standard, regardless of provider. While it's true there's no real other choice within Baltimore City, home internet access isn't really metered by person but by household. If you're lower income, there may be some subsidized plans available for you that are much less expensive.
