Yeah, because satisfying shareholders is more important than providing a quality service. Entropy exists even in digital systems. Maintenance is a must, and the easiest thing to overlook is the people who use your services (providing them value) when the people who pay for the value the users provide as the ones putting money in your bank account.
It's too easy to forget that if you do not take care of the users, they will leave and take the payers with them. Right now it's hard to escape Google.
But a little river carved the Grand Canyon, and as more people leave the services and provide easy to use alternatives, more people will follow. My guess is that, even though it might take 20 years if Google does not redirect their focus to be more equilaterally supportive of their users then Google will inevitably become a modern Yahoo.
