I think you are right on the money. Most posters will not agree and they have already made their point. Bvtk would not mention Google if they were not working with them directly. Time will tell if we are right or not. Don’t listen to the nonsense posted here. They know nothing about what is going on day to day.
There is zero evidence to think that google is interested in BVTK's product. BVTK's product is old and outdated, and has had no staff working on maintaining it or upgrading it for years; that google would be interested in it sounds like a bit of a joke.
The agreement with google is a marketing one, and that's it - they'll sell them ad space or something like that. To suggest anything else is just shameless pumping.
