Most of us in Lemmy know the importance of privacy and owning your devices in a big tech owned world (me included) but for once I thought to make the opposite question and ask if there are products by them that you actually use and enjoy them.
Important to say, I mean products you use even though there are alternatives, not monopolies like YouTube.
I have too many to name honestly but one that comes to mind (but not really “big”) is a travel router.
It’s amazing being able to VPN into either my cloud server or home network all over an encrypted WireGuard tunnel. I use the same SSID/password as my home network so that I only connect the travel router itself to whatever network (Ethernet, WiFi and even hotel WiFi with the terrible portal) and all my devices just automatically get online.
