I understand that it may be problematic sometimes but this was very smooth. I didn’t even say anything.
A: what’s your number for the whatsapp group Me: I don’t have whatsapp because of facebook. B: ok, we have to use signal then A: ok
And that was it. Life can be very easy sometimes
There may have been discussions around it beforehand. I didn’t ask why it went so smooth.
What you didn’t realize is that your value to the company is way more than you realized.
Often times people have resolved all the rational arguments to act on a decision but lack on an emotional excuse to figuratively pull the trigger. I’d bet on someone high up had already made up their mind and you not using WhatsApp was the perfect excuse to just have the whole team finally migrate.
