From Qt 5.15, The Qt Company make their offering a bit more inconvenient for FOSS users. They announced three changes:

A Qt account is mandatory to download binary Qt packages. The offline installer is not available to FOSS users any more.
LTS (long-term support) releases are not available to FOSS users, once the next minor or major release is out.
Small business pay 499 USD per year, if their yearly revenue is less than 100,000 USD and they have less than five employees.
