An unintended side effect of Twitter becoming paid is it makes existing accounts more valuable. It may be more convenient for bad actors to purchase hacked accounts rather than make their own. Verified accounts used to face a lot of phishing attacks, but less so now you can just buy verification.
If phishing of regular Twitter accounts does become more common, it's going to absolutely suck for users. Previously, it was near impossible to recover a hacked Twitter account when they actually had a support team. Now, there's absolutely no way they could handle an volume of support requests.
