Recently, Apple launched a new update of the MacBook Pro and discovered that they did more than just hit the specifications. They have also made further changes to their troublesome butterfly keyboard mechanism to prevent the infiltration of alien debris and the problems that come with it.
If you've kept up with this or if you've unfortunately owned an affected MacBook laptop, then you know that a little bit of dirt or gravel will quickly bring this keyboard to your knees, either to prevent a key from working or cause double presses. On top of that, it's also almost impossible to operate these keyboards without taking or sending it back to Apple. Although this issue has not been traced among the public as Antennagate and other Apple controversies did, it has become a real problem for Apple in technical pressure, among technological enthusiasts and recently, even among some hardcore Apple fans.

I can't say if Apple really does or will eventually, but they finally take some steps in that direction. First, they announced an expansion of the keyboard service program to include the 2018 MacBook Pro and Airs. This means that any owner of a Mac laptop with a butterfly keyboard can get a repair if they need one. This should not be necessary, but at least Apple does the right thing and ensures that the one-year warranty is not in the way of dealing with an obviously erroneous design.
Second, the keyboard is, as mentioned above. It's not quite clear what specific issues Apple is trying to address, but there are a couple of changes that have been revealed by iFixit's latest teardown. I will leave the details to them, but they believe that Apple's statement of "changing materials" to improve the keyboard applies to both the former silicone (now likely TPU) cover and the metal dome switch which actually triggers the key response. If you're interested in nuts and bolts, have a look at the iFixit article. They always do a beautiful job of breaking down everything in detail and then summarizing every bit.
Time will tell if these latest changes are the magic bullet that will eventually fix this keyboard. I can't say that I or many other Apple users will have great confidence that they will until we see any definite proof over a long period of time. Unfortunately, Apple achieved that skepticism by drawing this keyboard situation out with long periods of inaction. I can say this with confidence: This is Apple's latest shot to get its butterfly keyboard mechanism to work. If these changes do not get the job done, they must completely discard this design and start again.
