It seems extremely likely to me that Bruce wants Marc out and Bruce seemingly questioning whether there was something shady or not with regards to debt Susglobal started taking out a year ago makes it appear that he may have a way to give Marc the boot. Or at least that he thinks so. And I guess he sees something salvageable in the company if Marc were gone.
If he wanted more ammo against Marc, he could start with the way Marc has consistently provided non-public info to shareholders over the years and failed until Q1 of this year to disclose legal actions against the company in filings. Marc got slapped by OTC Markets at one point but IMO he's lucky that he's never drawn the scrutiny of the SEC.
