The six-time world champion was preparing to kick off his campaign against Ding Junhui on January 13 at Alexandra Palace.
But new Covid-19 regulations in the capital mean that the tournament has been moved to Marshall Arena in Milton Keynes, with no fans in attendance.
This is where every snooker tournament has taken place since last August when O’Sullivan won his sixth World Snooker Championship at the Crucible.
The Englishman has previously slated the venue – and the current World No.3 was at it again before the tournament location changed back to the Buckinghamshire town.
Speaking to Eurosport , O’Sullivan said: “It’s disappointing there won’t be any fans at the Masters because you are playing in such a big venue and it’s going to be empty.
“But I’ve got to be honest, anything is better than going back to Milton Keynes.
“I’m not going to moan or complain in being able to not have to go and play snooker in Milton Keynes just for the odd week.
“Hallelujah! Halle-bloody-lujah! Honestly, it is okay and it has served a purpose, but to have to play every event there is just hard, hard work for a lot of people.”
O’Sullivan went on to fire a warning to tournament organisers ahead of returning to the Marshall Arena.
He added: “If this is going to go on much longer, it would be nice to have at least three tournaments in the whole year away from Milton Keynes.
“We can go to York, the Ally Pally and the Crucible – three tournaments where you don’t have to face Milton Keynes week in, week out.”
O’Sullivan and the other snookers players have been working in a player bubble during tournaments to prevent the spread of the disease.
And the 45-year-old made a brutal comparison last month, with: “This is like prison – an open prison.
“I used to go and visit my dad quite a lot and I watch players who are here now who aren’t playing until next week.
“They have their little bit of food and going up to their room and it’s lonely, it’s horrible.
“It’s like you could go out and get a little job in a charity shop and that’s your privileges. Otherwise you are in here hitting a few balls and having a chat with the lads.”
