With regards to GOG and privacy, though, it's worth nothing that GOG write that they "may use Google Adwords, Doubleclick, Sizmek Versatag, Yandex.Metrica, Twitter Pixel or Facebook Pixel and other similar technologies" as well as "Google Analytics, Google Optimize, Matomo, Hotjar", and that they incorporate either the privacy or cookie or ad policy of most of these services by reference into their own cookie policy:

So if they really are a privacy- and consumer-oriented company, that must be the slip-up of the century.
But if your games don't need a network interface, who cares?
maybe on their website (which you can block, unless you use google/etc payment methods)
I just put some money in a gog wallet once, then block everything and talk to gog only for browsing, buying games, etc
I think we should support people who are uncomfortable about this stuff, don't ridicule them with "tinfoil hat much?" type sentiments
By the way, GOG.com treats you well wrt cloud/privacy/etc. All games they sell are drm-free and can be downloaded, installed and played offline.
