Part of what? A recent comment where? Can you actually point to anything
Microsoft have ever done that can be demonstrably proved to be done
solely with the intention of blocking 3rd party clients? (I hate to
sound defensive of Microsoft here, but FUD should not be allowed either

The change was made because their SSL certificate was expiring, so they
renewed it, I guess that counts as "valid security reasons". The reason
they didn't detect (and so far don't seem too concerned about) the
mis-configuration of the server(s) is that their primary client already
recognizes the new intermediate certificates that signed the new SSL
certificate as trusted anyway, so they don't have a problem with the
fact that the server(s) are still providing the old intermediates in the
chain. But the reason their primary client trusts the new certificate is
simply because they ship & update their primary OS with their own
intermediate certificates too.
