So far so correct. But do I care about their market capitalization?
Since we are not talking about investment banking I'd dare say: no.

How about "Willingness to pay for products or support"?

In that regard Apple and Microsoft rank very low - they are almost pure
software suppliers, not customers. Amazon may buy some support, but
AFAIK they do most of it in-house.

So who pays lots of money for Qt-based products and support?

All kinds of industry who have to maintain expensive machines (big
players may be names like Intel, TSMC, GE, GM, GSK, ...). Vendors who
create higher-level Qt products and support companies surrounding these.
Companies producing entertainment products that will be Qt based. Etc.

While you will find a lot of companies that want the newest and hippest
features on the newest OSes, you will also find quite a few behemoths
who are willing to toss large sums after very old systems.

Here is a challenge for you Thiago: on Monday contact the manufacturing
side of your company and ask them for a clean room tour in one of
Intel's many fabs - once there take a very close look at the control
screens of the machines in there, note the systems they are running.
