In QA96 has been said that much of intellectual property rights are still with Canonical and UBports sublicence it. Would it be theoretically possible that Canonical kills UT in future simply by withdrawing this sublicence ? What will happen when some future Pres. of the USA impose sanctions on Europe/Germany similar as it happened with Huawei ?

I have Volla with UT and I use nextcloud server at home. Calendar sync wors, but it terribly lacks contacts sync. Should i expect full support for nextcloud in near future ?
