No, you can still purchase a standalone product currently called Microsoft Office 2021. I just did recently from their online store. Nephew works there so I piggybacked off his family friends plan and got the whole suite for about $50. I am opposed to cloud based software so I always look for alternative packaging
I've used ooen office for ~20 years.
Android I think Feeoffice could be the way to go. I'd be concerned that they'll have to make m8ney somehow.
I've also used libraoffce, which is really good.
