Google was the first to move that way, now Microsoft has cancelled its Bootstrap program and even Facebook has done away with its Startup Accelerator program in favour of 'Contact your nearest Accelerator/VC we approve of' model.
I was personally benefitted by Facebook's aforementioned Accelerator program. I applied for my previous startup's privacy focused chat-app-network dating platform for their bootstrap phase, but they directly approved it for their Accelerator phase through which I received $80,000 worth benefits incl. $15,000 AWS credits on which I ran my product; these kind of help makes life or death difference for a disabled soloprenuer from a village in India running bootstrapped startup(Facebook doesn't know this).
Now anyone in my position is at the mercy of some Accelerator or VC.
