The original statement that got everybody nervous about "token swaps" was:
later retractedhttps://support.poloniex.com/hc/en-us/articles/360043406513-Coming-Soon-STEEM-Token-Swap
As seen on 2020-02-16
It should be noted that once "token swap" was retracted, there was about a week prior to the softfork where Tron would pivot to the term "atomic swaps."
The retractions were an attempt by Tron to deescalate. But at no time did Tron acknowledge the specific claim that there was a lack of disclosure involving the transfer of the "dev fund" which was the bigger issue to the witnesses who froze the accounts.

Regarding the use of Tron founder stake to remove three super representatives (SR):
I'm not convinces that Tron fully explained the security issue around this action. I suspect these SRs were routing (stealing) fees from malformed contracts. But I've never gotten any confirmation of this. The reason I think this is so is due to certain TIPS (Tron Improvement Proposals) that coincided with the java-tron releases blocked by these SRs (specifically, TIP-37 and TIP-54). Again, all speculation on my part.
Apologies for my late response, but a big delayed thank you for your help @inertia!
