When you're in the industry, especially a leading innovator in the industry, it's infuriating to see an inferior product being recommended, one that you can credibly suspect doesn't even deliver on the promises, but in your attempts to discredit that product you'll sometimes come off as a crusading zealot, to the detriment of other content you've packaged with your commentary.
There was little need to call out Telegram in the post by name, because it does instantly re-frame the conversation, and in a forum some of the conversation will continue down the new path, as it does now. That's a mistake in this format, and it does come off as a defensive misdirect made in the heat of argument. A place to reinvigorate this criticism in light of the new revelations is one's own personal -- or even professional -- blog, where you can start off on the high ground.
