Nope. Bad logic. I love Dropbox, but welcome to capitalism. Dropbox could exit to Google in an instant. They could have for years. The only reason they haven't

Nope. Bad logic. I love Dropbox, but welcome to capitalism. Dropbox could exit to Google in an instant. They could have for years. The only reason they haven't is because they want to maximize the risk adjusted returns for their shareholders. Since Google can't aquire Dropbox at a reasonable price, yet finds it necessary to have this type of service built into their offering, they are more than ok to compete.
