I am also skeptical (despite having 0 faith in the new owners). However, I am a bit confused: why would new ownership alone cause technical issues? It seems like they set new requirements that required new software. Even if the reqs are content-agnostic, I am curious what they are and how they differ from the previous tiktok.
Data migrations, new staff permissions and policies, merging AWS or other cloud accounts and their complex IAM policies, enrolling devices into new corporate networks, Okta setup, corporate firewalls. There are hundreds of reasons that moving to a new corporate ownership can cause technical problems.
