tWitch's Friends Slam Todrick Hall for Speculation About DJ's Suicide

Friends of the late Stephen "tWitch" Boss are calling out his "pal" Todrick Hall ... after he suggested the pressure around Ellen DeGeneres' workplace scandal might have been a factor in tWitch's suicide.

For those unaware, Todrick made the implication this week while promoting a new reality show he's doing ... telling Page Six he believed the public calling on the DJ to stop supporting Ellen took too big of a toll.

Referring to tWitch opting to take his life, Todrick added, "I don’t know what was going on in his life that may [have led] him to make that decision but I do understand."

A source close to tWitch tells TMZ ... it's extremely negligent and self-serving of Todrick to assume he knows what led to tWitch's death. The source also found it unfortunate he would speculate, especially while promoting his own project.

We're told tWitch loved his time on "Ellen," and had a ton of respect while working on the series ... pointing out he was even named co-executive producer in the final season.

As we reported, tWitch left a suicide note behind when he passed, which we're told referenced past challenges ... without going into specifics.

You'll recall, Ellen was accused of creating a toxic work environment while the show was running, as several former employees alleged racism and intimidation. tWitch, however, stood by the talk show host.

Ellen also expressed her intense heartbreak after his death ... telling people to love each other as she continued to mourn in late December.
