I don't believe that at all. The obvious reason why they discontinued Android support is because Apple isn't interested in continuing the existing B2B business. They're interested in the technology and the team and they're likely to integrate it into their own developer tools and offer them for free.

Why would Apple invest resources into making developer tools for other platforms? What's the real upside if Buddybuild continued as is and they tried to scale it up? Hundreds of millions in revenue per year? That's a drop in the bucket. Buddybuild's value is strategic, not because it was going to make a financial difference to Apple.
