For b2b sales, as this IBM initiative seems to be focused on, I think there are a few things going on. This is all my opinion, based on first hand observation during the height of COVID WFH in enterprise sales, for a vendor that did very well during the lockdown period but which "returned to customer" as quickly as possible.

First, there was a lot of nervousness about long-term sales pipeline creation during lockdown. That anxiety was not completely unreasonable. While we had a lot of contact with our customers over video conferencing, etc., it was tactical and project-focused. The thought was we were getting locked out of all of the hallway conversations, lunches, conferences, trips, etc. where you tend to learn about new projects, problems that need to be solved, etc.

Second, sales leadership is a travel-heavy business. I spent 3 - 4 days a week, almost every week, on the road. That came to a rather abrupt halt in early 2020, which was fine with me. I never really liked the travel. But, as far as I could tell, I was in the minority in that belief. The job selects for the road warrior, and most of my peers and bosses could not wait to get back on the road.

And, so, I think people took a plausible hypothesis (pipeline will evaporate if we don't spend face time with our customers) that they wanted to be true, and ran with it.
