I've personally seen most of these jobs ain't truly remote either, since they restrict core jobs to local regions mostly so that they can call employees at times.

The good thing is, it is growing; the not-so-good thing is it is still being looked down upon and not considered as the best option when organization grows or achieves X amount of revenue. You know what I mean.

I work as remote developer, or remote a dev agency for my customers (mostly in the US) and they also strive for having their own On-site team once they raise big funds, no matter how good we work from our location; so some hard realities are also there. :)
