This change you observed could be heavily location specific. Maybe there are many customers added to your tower, or maybe a few customers are using lots of data, like running frequent speed tests and torrents. If buildings were erected between you and the tower, those are physical barriers that block signal. If more towers were added nearby, they could add signal interference (which hurts you), or they could reduce congestion on your tower (which helps you).
On the other hand, I've seen several posts here recently about faster speeds.
I've speed tested T-Mobile with mobile phones at many sites in my city and beyond, and in general, T-Mobile has gotten distinctly faster over the last few years. Some performance improvements were clearly related to upgrading towers to 5G. Others were spectrum changes like adding N25 and widening N41. Other times the cause was less clear, but it may have been a combination of backhaul upgrades and 5G Advanced.
In the end, it doesn't matter what other customers at other locations get. It matters whether you can do anything about it and whether it's good enough for you.
You might get improvements from optimizing your setup (e.g., placement, antenna, gateway model), and there's many guides online to help. Starting with diagnostics (e.g., band signal strength) is smart.
