Great catch. Thank you for the warning.
Every single time I check in here, I see a blatant scam against the users being pushed. Last week it was "lets get rid of SteemDollar", the week before it was "removed 10 more days of replies", the week before it was "change the payout scheme people invested for", and a few weeks before that it was "disabling edit, delete, and reply on old posts". Once you line up all the actions, it is clear why so many users have left.
Making this Opt-Out is simply to grab control of all the voting power THAT THE DEVELOPERS CHASED AWAY with "it's beta" excuses, crappy customer service, rule changes, investment payout changes, disabling control of users own content, and actually disabling replies to 20 day old posts.
Chasing users away should not be made profitable. This opt-out bullshit must be stopped.
