Google was very consistent in its approach to the education market, making it easy for teachers and students to get on board.
My oldest child's public elementary school started having kids use Google Docs about 8 or 9 years ago. I purchased a Chromebook not long after so my Mac wouldn't be used for homework, and the younger sibling got a free Chromebook handed out by the school at the beginning of high school.
Docs, Drive, and a bunch of other G Suite for Education tools are now the foundation of both my kids' classroom experience. Neither has ever asked to use MS Office for anything, and no one in our family uses the equivalent Apple office apps.
Macs and PCs aren't banished from the school system, however. I see them in libraries and certain classrooms where special software or heavy-duty compute power is required. My oldest also used money from a summer job to purchase a new MacBook Air a few weeks ago to prepare college essays and to use at college.
