Just because it seems like a good price for you doesn't mean it's a good
price. Reducing the licence price to one tenth what it is today could mean the
revenues for the company reduce to one tenth too, which means the development
team might need to reduce to around one tenth what it is. For a licence one
tenth what it is today, you have to prove that sales would be ten times bigger
or more. Do you have such proof?
You have absolutely no information on how elastic the Qt commercial price is,
so kindly don't speculate on what price would be good. The only entity that is
close to having that information is the one doing Qt sales in the first place
and even then I don't know they know very well.

No, they aren't. Just see that someone else posted on this thread that they
were paying for a year and then decided to stop doing so because they weren't
using the licence or support. That's the big issue: why keep paying for
something you're also getting for free? Companies don't pay out of the
goodness of their hearts.

What makes you think that the automotive field isn't exactly the worst field,
using Qt in a large set of devices and not contributing code nor paying for
And how do you convince them to pay more? You have to give them something they
want and wouldn't otherwise get for free. Like a release supported for a big
number of years. At least for the automotive industry, allergic to the
(L)GPLv3 as it is, there's one other: the incentive of a licence that doesn't
have the TiVo clause.

Conclusion based on opinion, not data. Sorry, this is not how it works.
