There has been new information since that blog post which has reaffirmed the "this is much ado about nothing" takes because Ofcom have said that they do not want to be a burden on smaller sites.
"We’ve heard concerns from some smaller services that the new rules will be too burdensome for them. Some of them believe they don’t have the resources to dedicate to assessing risk on their platforms, and to making sure they have measures in place to help them comply with the rules. As a result, some smaller services feel they might need to shut down completely.
So, we wanted to reassure those smaller services that this is unlikely to be the case."
