Why is it "going to get worse"? A 4-second delay might need to be done for launches more frequently, but I don't see why the delays would get longer than that - debris moves out of the way at the same speed regardless of how much of it there is. This doesn't seem like a big deal. If a 4-second delay risks killing your mission then you probably should have designed the mission with more leeway in its launch window to begin with. There are a huge number of technical issues that could easily cause a 4-second delay.
Of course, that doesn't result in a headline that draws clicks.
Edit: I just read the article. "It's going to get worse" doesn't appear anywhere in it. You just made that up.
