You can see everywhere that more and more companies are not including a Scrum Master in their teams. Others renamed the Product Owner role as Product Managers or Product Marketing Managers, and these don’t play the same rules as the PO. Many are even dropping Scrum and moving to a plain Kanban.
Software industry got fed up with Agile Coaches, stiff ceremonies, games and multitude of meetings. I don’t blame them for doing so. I personally reckon you’ll do it OK if you pick the best of each framework and remove any practice that is not working for you or it is not as productive as it should be (Law of Diminishing Returns).
Keep stuck with the basics: deliver software frequently, welcome changes, work close to Business people, and more important than anything, keep it neat and simple. You’ll be OK.
