I literally couldn't find this announcement after spending a bit of time googling openledger delisting steem sbd etc.

If almost no one on Steem caught it it's definitely not public enough.

Is this their account https://steemit.com/@mtopenledger ? You'd think seeing as they were active just 2 months ago to shill (roughly when they decided to delist us), they'd also make a delisting announcement on here as well.
