I was curious and did some research. Tapatalk was re-purchased by the founder. Probably good news for the app. Almost all the forums that are removing support are owned by a company called Verticalscope which apparently have bought up thousands of forum sites on the internet over the last decade. They also own the forum hosting software XenForo, and the competing app to Tapatalk, Fora. Looks more like this Verticalscope company looking for an opportunity to consolidate than issues with Tapatalk. Apparently almost the same message verbatim was posted in most forums, which made some people suspicious.
