That is sadly true. I bought a slightly used MBP 15" 2015 from a former colleague at the start of 2018 and have been very happy with it. Every single MBP after 2015 has been a disappointment, be it for the removal of the MagSafe charger, the godawful touch bar, the very subpar keyboard, or no upgrade to 32GB RAM.
Sure, they finally added the 32GB RAM variant several days ago but… butterfly keyboard and touch bar for the high-end models! Yeah… I’ll skip.
