To be honest I don't think anyone will really care too much about Google killing a VPN product there's probably companies out there better suited to offer this as a service. I think the one that still bothers me and I think was a big mistake considering there cloud computing platform was Google Domains. Wasn't that profitable product and perfectly suited to be fully integrated into GCP?
Edit: As someone else has stated it's good that they try things and try different products and I think it's good that they shutdown products that they are not good at running
