Would not surprise me in the least if most of the webcam products on the market were fronts just like Twitter… Ostensibly a social media network, yet a de facto communications propaganda & surveillance network in actuality. Plausibly but not practically functional. The fact that we finance it all only heightens the laughter behind the scenes.
Generally speaking, however, I will say that most of my wyze installation base is pretty reliable. The most glaring issue I have faced is with cam pan v1 firmware. Between spring of 2019 and spring/summer 2021, event capture by motion detection was broken. Literally had to keep it on back level firmware until last August when I took yet another stab (despite 3-4 successive brickwares preceding) and they seem to have fixed that issue.
Currently I am dealing with erratic wco v2 & solar panel charging in this thread. Oddly, my rig worked perfectly for 2 weeks and then started gradually depleting all the while showing a charge symbol… 
Also, the odd random products going offline… Most notably this outdoor plug as well as periodic cam pan v2 fits.
