Black horizontal line on bottom of 2017 Macbook Pro screen

I've had this 2017 13 inch Macbook Pro since 2017 and just a couple of months ago black horizontal lines started appearing at the bottom of the screen:

My worry is that these lines will continue to get worse and worse until I have to end up getting a new machine when the issue wasn't even my fault.

From other forums where people are having the same issue for their 2016 or 2017 MBPs:

Someone on this particular forum said the issue is due to " a T-CON board issue. The design of this series places part of the displays logic within the main case placed just above the heat transfer fins of the heat sink. So when the system is running hard the heat can boil up cooking the T-CON board. Sometimes dust buildup within the fans and fins block proper cooling. If you are just getting the static lines you want to make sure you get your system cleaned and reduce the processing load. Also make sure your rear area is clear of any blockage as well"

It seems like many other people or having the same problem and it definitely seems like it is a design flaw having to do with the overheating of the machine. Despite whether the user from the forum is correct, I have already reset the SMC and contacted Apple support who simply told me that I can fix the screen for $500 since I am out of warranty. If I let my computer rest for acouple of hours, the lines disappear but only to reappear after 1-2 hours. The applications I am running aren't even intensive which makes me regret paying over $1500 for a computer that I thought was made for performance.

This is extremely disappointing that Apple won't admit to their mistakes and instead, force their customers to pay even more money to fix a problem that shouldn't have existed in the first place. I really don't know what to do anyone in terms of fixing this issue and I wanted to just see if anyone here is having the same problem as me and whether or not they know if a recall program is going to be implemented soon for this issue. Some extreme solutions that some people are saying is to install fan control program and tweak the fan control so my MBP overheats less frequently..
