I guess for me, it being closed-source and the fact that the Bitwarden password manager and now Bitwarden authenticator are open source. Truthfully, I just see how they handled the desktop version of their Authy software, giving no fucks if consumers wanted it or not, being a big red flag of what could come after. Having used Bitwarden for years now, and giving them $10 a year, makes me more biased and inclined to use their other software, since they’ve never let me down. :)
