For example, let's say I'm a big for-profit selling shovels. You're a naive non-profit who needs shovels to build some next gen technology. Turns out you need a lot of shovels and donations so far haven't cut it. I step in and offer to give you all the shovels you need, but I want special access to what you create. And even if it's not codified, you will naturally feel indebted to me. I gain huge upside for just my marginal cost of creating the shovels. And, if I gave the shovels to a non-profit I can also take tax write-offs at the shovel market value.
TBH, it was an amazing move by MS. And MS was the only big cloud provider who could have done it b/c Sataya appears collaborative and willing to partner. Amazon would have been an obvious choice, but they don't partnership like that and instead tend to buy companies or repurpose OSS. And Google can't get out of their own way with their hubris.
Because what you just described would happen the same way with a for-profit company, no?
