Telegram is no better than WhatsApp when Apple & Google dictate what groups are censored on Telegram for it to remain available in Apple & Google App Stores.
Certain channels I was following now only display "Unfortunately this channel couldn't be displayed on your device" due to censorship. I can view them when I login to Telegram web app, but Apple & Google forced censorship on devices. Rendered Telegram useless in lots of ways as they caved in.
Signal is the last remaining privacy focussed messaging app, but hardly anyone uses it apart from criminals & Government officials, which is the same thing really.
