Covid normalized remote working, but also didn't necessarily make companies and teams _good_ at it; I suspect RTO is easier than fixing the fact that your org sucks at remote work. It is hard to do well! it requires different strategies than just picking some software.
Partial/voluntary RTO also is the worst of both worlds: people coming in the office to sit on Zoom with colleagues who never do. Ultimately, I think RTO is a valid choice as a company, and a lot of orgs are coming to regret not messaging from the beginning that remote would be a temporary arrangement during the pandemic.
