Because that thread is one of the first search results in Google and can only harm their reputation. It documents their failure to deliver what they promised to investors on here and shows most of their ardent supporters on this forum slowly turning against them after realizing they were duped. They basically ripped off Telegram and made a few simple modifications. Look at the last update Android 3.0 update that was announced; new color schemes and a hide messages option. The current version in the Google Play store is 2.9.4, which was last updated March 22, 2016. So in 2 months, the best they could come up with is 2 measly features. Notice that the title of the app is 'Telegram with GetGems' and not simply 'Getgems' or 'GetGems with Telegram'. Even their title gives priority to Telegram over GetGems...
On another note, where is the source code for this project and who is the team that is supposedly working hard at it? A novice with no programming experience could figure out how to add the 'new' features they announced within the 2 months since their last update.
