I’ve been mainly happy with t212 since I joined nearly 12 months ago. Opened my eyes to a whole new world and it’s been an incredible journey so far.
I’ve seen the growth and popularity expand at a rate so have been waiting for various fees to pop up. Felt inevitable really. 400k - 1.4b clients. Something was bound to change.
The only issue I have is with the posts disclosing your popularity and profitability (which is great news! Business is clearly booming!) then wrap the message up nicely with “…while remaining completely free 
”
Going forward I think it’s wise not to write such things as personally it breaks the trust with your clients thus in turn leaves other things you say…
(Quote above from @AlexK )
“Rest assured, we are not going in that direction”
(Regarding more fees to potentially come)
Feel lacking in credibility.
Maybe be a little bit more transparent with your clients 
thank you.
