Google One VPN will be discontinued, Pixel VPN remains with upgrade coming

Seriously, at this point it's a self-fulfilling prophecy. None of the dedicated users start using a Google service because they know it won't last. Or maybe they do use it to play around with, but they certainly don't recommend it to their less enthusiastic social circles. Either way, this severely restricts how much the service can grow by word of mouth. Thus it doesn't get enough users for Google to consider it viable, and they shut it down. And next time, people are even more cautious about getting invested in a Google tool.
