Some people definitely are. The typical reasons are some combination of (1) Subscriptions are more expensive and restrictive, (2) discovering "good" content has gotten harder, (3) fan favorite shows are getting aggressively axed.
I have. My company wanted to begin hybrid next month, while I didn’t feel comfortable doing so until January 2022. When I initially broached the subject in May/June, they weren’t accommodating so I gave my notice. (Hybrid require a big move on my part.)
Recently, they’ve pushed back return date to November at the earliest and become more accommodating, but that ship has sailed, unfortunately.
