The Historicity of David, Pilate, and the Philistines

I've looked at the discoveries of things like the Tel Dan Inscription or the Pilate Stone which testify to the existence of David and Pilate. I read that before such archeological discoveries, the existence of people like King David and Pontius Pilate was disputed. Now, it seems that most scholars accept the existence of David, and all accept Pilate existing from what I've seen. Apparently, starting from somewhere around the 17th century, scholars were arguing against Biblical figures existing. They also argued against the Philistines' existence. Every apologist I encounter who brings up these discoveries starts off by saying "Skeptics used to say 'x', but because of these discoveries, we have evidence that 'y' is true, so they agree with us now." But I cannot find many examples of skeptic scholars in the past who have denied the Philistines, David, Pilate, or many other people whose existence is disputed. Maybe I haven't done enough research. But these attacks on skeptics are found on basically all apologist websites defending the validity of the Bible. Here's one example of such a website from a good defender of the Word: https://coldcasechristianity.com/writings/a-brief-sample-of-old-testament-archaeological-corroboration/ Could someone point me toward some evidence that the scholars doubted the existence of David, Pilate, and the Philistines back in the day? Thanks.
