I have a 2017 base MBP, which also has 2 USB-C ports. On that machine, I think it is fair to characterize it as having a single port, since you have to plug it in all the time. On the M1 and M2 machines, however, this is not quite as fair a characterization. After all, the battery life is ~2x that of the Intel MBPs. So you can definitely plug in your iPhone into one port and an external HD into the other and do a backup without worrying about the MBP running out of juice. Still, I think it's pretty silly that the new MBA has MagSafe + 2x USB-C and the base MBP is still scraping by with just the USB-C. Even the original Touchbar MBPs had more connectivity than that! (The base MBP didn't have the TB, blessedly, so it was only the 4-port machines that had this 'upgrade'.)
