I think it is quite straightforward. The issue is, I believe, payment of bills for Internet at your home or for staff at their homes, which, given the circumstances that Canadians find themselves in, having a difficult time paying bills and with inflation at the high rates it is at, seems to be something that should be a personal expense and not tied to your job as an MP or as staff to an MP.
That being said, some MPs have spoken to me and said that at the beginning of the COVID-19 lockdowns, etc., when they had to work from home, being in particularly rural communities, they had to upgrade their Internet. One MP even had a tower erected in his backyard in order to facilitate that. However, those costs were incurred in the past. Now that we are where we are, our feeling is that this should be a personal expense and should no longer be charged to members' budgets.
We as a party have taken the step of telling our members not to claim those charges anymore. I believe others have done likewise, but I don't know the status for all the parties.
