this kind of reminds me of what they did to Cortana. I might be the only one, but I loved Cortana and used it multiple times a day since it was first released with Windows 10 1507. Then, M$ started lobotomizing Cortana. First, they took away its integration from the start menu, then they started taking away her features. at the end, not even the voice activation, which i used constantly worked. and then they killed Cortana off completely. they put CoPilot in Cortana's place. Do you want to know how much I have used or found CoPilot useful? not at all. Cortana was much more useful. If CoPilot had the digital assistant features that made Cortana so useful, i would use it constantly.
Sorry.... I got off on a bit of a rant...
My point is I bet it won't be too long before MS starts lobotomizing CoPilot as well. either letting paid users have full access or just removing its functions for everyone.
