Economist and former RTE employee David McWilliams has told staff at the embattled station to "grow up and face the real world".
Mr McWilliams, who formerly presented a show on the national broadcaster, was responding to news of cuts at RTE and an interview of Director-General Dee Forbes by Bryan Dobson on RTE Radio One's Morning Ireland.
And he also hinted at the acrimonious nature of his departure from the station years ago.
He tweeted at the programme and said: "I’ve been fired behind closed doors by RTE’s so called executives and none had the balls to tell me themselves or explain why.
"Get over it. Grow up and face the real world!"
Mr McWilliams is widely credited with predicting the most recent recession a decade before it occurred.
The author and broadcaster has also stated “the property market will burst again”.
Last night it was claimed RTE is planning to cull 200 jobs and slash top presenters' salaries by 15%.
Releasing a statement to respond to a "leak" to the Irish Times, RTE confirmed it will close its Limerick studio as part of a major financial restructuring to save €60 million over the next three years.
This is part of a wide range of cuts and changes on what RTE's Moya Doherty described as an "ambitious journey of transformation which will support it to provide audiences with the quality public service broadcasting that it wants and deserves".
