Probably because of the profit margin and overall increase in bandwidth
Since they lowered the broadband price, you can see the overall quality drops like bombs in the middle east
No more fibre wall box, more low quality devices etc
At the same time all the packages increased in speed means more bandwidth is required
Lower price, higher bandwidth requirements, lower profit per customer
From the standpoint of a business that has monopolised the market since 1960s, I understand
From the standpoint of a user, I cant accept this

Just switch to another telco if you are able to do so
I tossed my Unifi to failover after subbing to Allo, no more CF congestion, getting 6ms instead of 150ms+, latency to other websites seems to be 50% lower as well
Why pay an ISP that refused to fix known issues

How about routing to China sites and international routing?
