I don't mind subscriptions as they're more valuable to the organizations I support than a similar dollar-value of one-time-gifts. Though I do get why people in precarious positions (e.g. low paid workers, founders, or many people in high cost-of-living areas) would prefer not to use them.

But the only reason I can imagine routing charitable giving through work is to take advantage of company matching. At a past company that did 100% dollar-for-dollar matching (up to something like ten thousand dollars) I was happy to shift as many of my donations as possible through work to direct more of the company's giving towards my preferred charities. At my current company that does 0% matching there's no reason for me to involve work in my charitable giving.
