AITA for leaving a team member out of conversations at their request?

I manage a large team in the IT sector.

I have a weekly Friday huddle that I set as a 1 hour meeting on everyone's calendar. Due to how billable time is a BIG thing for these groups, the 1 hour time block makes sure they don't feel rushed to get back, but the content never takes more than 20 minutes.

After my spiel, I say "well, that was quick! any big plans for the weekend anybody wants to share?" People start chatting, the conversations gain traction, and typically fill the rest of the hour. People generally like it. I leave soon after I'm done with my portion of the huddle. It's the only time all week the teammates chat with each other as a group.

6 months ago, during a huddle, I had "Sam", who normally doesn't participate in the after-huddle conversation, (which is fine), respond via what I felt was an outburst for asking the group if they had any big plans for the weekend because Sam "never does anything anyways, and all that question does is point out that they (Sam) have no life", and finally concluding with "I'm here to work, I don't want to be involved in anything not related to work." I said "I understand. Alright team, That'll end this weeks huddle."

For the next two months, I ended the meeting promptly.

I then was told by several staff in 1 on 1s and in other conversations that they like the after huddle conversations, and they would like to still have the rest of that hour to chat.

Based on this feedback, I sent out a survey, and asked people if they wanted to have a "fun huddle" after the "business huddle" on Fridays, and if so, to add their email. Due to this not being work related, and due to the team whispering that they sincerely hoped that Sam didn't prevent this from happening, I didn't add Sam to the DL.

Everyone on the team except for a couple of people responded to the form- but over 90% of the team were in favor. So, the next week, I scheduled two meetings- I shortened my huddle to 20 minutes, and put a 40 minute "miscellaneous discussion" meeting on the calendars and sent it. I gave a code to bill to, the team was thrilled.
As Sam did not want to be involved in non-work related huddles, I didn't add them to the meeting.
Well, that day came and went, the Misc. huddle was super fun (without my knowledge, people brought snacks) and Sam came and found me the following Monday.

Sam informed me that I was an absolute jerk for setting up a second huddle and not letting them know or inviting them. They felt left out, they felt as though I was singling them out, and overall that I was being an asshole. I sincerely didn't expect this, so I paused the conversation and said "Sam, I am not willing to have this conversation. I respected your conditions and didn't include you because it was not a work related meeting.

Sam hasn't said a word since. I don't feel I did anything wrong, but they are clearly hurt. AITA?
