Tying as a legal issue has never made sense to me, and seems incompatible with private property and contract law. As a consumer, I don't have a right to an imaginary version of Windows without Internet Explorer that I wish Microsoft would build. Likewise, as a handset vendor, I don't have a right to an imaginary contract with Google where I get everything I want on my terms.

Tying laws, and antitrust broadly are a way for regulators to forcibly dictate what companies create. As stated above what's really revolting is this typically comes as a result of competitors lobbying to cripple the top player in the industry.
