I see what you’re saying but To clarify:

Transportation: they had a bus driver shortage and wanted the word out to fill the vacancies. Those with large congregations could make big announcements at service.

Reading programs: read to/with elementary school kids falling behind in reading during lunch.

Mentorship programs: non Christian orgs looking to put the word out to get more volunteers from churches

Hotspots: you’re correct in that Some churches did discuss their doors open during the week to allow students to come in an access classes/homework.
