It doesn't involve deploying "bespoke" applications written using GTK,
so no, it doesn't.

They aren't spending $Big Buck$ promoting its use, they're merely
deploying it.

In contrast, it is very much in the interests of TrollTech to actively
market Qt because that leads to them getting a substantial stream of
revenue from selling Qt licenses.

That is only true for applications being deployed on free Unixes like
Linux or FreeBSD.  If you are deploying applications on other
platforms, you're expected to build using the commercially-licensed
version of Qt.

And the matter of having to deploy software under the GPL very much
_is_ the reason why "UserLinux" rejected Qt as unacceptable for their
purposes, and GTK as preferable.

The only case where there _isn't_ a "lock in" would be if TrollTech
_did_ "go bust."  And if they did do so, they would _not_ release
under the GPL, but rather under a BSD license.

You are missing the point that this isn't a problem they would want to
"avoid."

What they very clearly want to do is to discourage people from using
the "free" version, and to convince them to use the "commercial"
version instead.  The nonavailability of LGPLed libraries is not a
"bug;" it is a "feature" in that it pushes people to send them money.
