Essential?
the Your Phone companion app, which has become an essential tool for Windows 10 and Android users
Has it, now? I have both Windows 10 (on a work machine) and Android, and I've never used Your Phone, nor do I ever intend to.
Based on the article and comments, it sounds like it's used by a rather small fraction of Win10+Android users. For how many of those is it actually "essential"?
Some of us - I know this is shocking - managed to get along just fine without smartphones at all, once upon a time, much less smartphones with "apps" for our desktop or laptop computers.
