I would be very surprised if it's deliberate. Updates to particular apps causes two pain points - Apps get more demanding and developers tend to focus on newer hardware models as people stop using older phones.
No answers as to what could be happening within iOS, but clearly it also gets more demanding.
As with all else start fresh and see where the breaking point is. OP stating that everything starts fine and then issues arise a few days later hints to a lack of resources (RAM usually).
How long is the battery lasting these days?
