How do we measure this sort of amplification objectively? How do we account for context? I would say that it's exactly the opposite, that through most of the history of the Arab-Israeli conflict (of which the Palestinian issue has been a sub-conflict) the Arab voice has been amplified over the Israeli. Israel has faced many boycotts, many attempts to destroy it, and generally as less than favorable in world public opinion.
It is maybe true that there's been a little shift with the collapse of the soviet union and the split in the Arab world. I would still say that Israel gets more negative coverage in comparison to other world events and even within the specific conflict.
Just a recent example, at some point during the Covid crisis Israel was extensively criticized for not treating Palestinians in the West Bank and Gaza equitably with regard to vaccine distribution. Nobody even mentions that Israeli Palestinians are treated equitably in this regard. Nuances are lost. Recently when Israel did agree to provide Palestinians with vaccines the Palestinians rejected them:

EDIT: And forgot to add my point, that this did not receive as wide of a coverage.
Lack of "censorship" also has a body count. What about all the Covid conspiracy theories? Should we give those guys a free stage on social media? Incitement to commit real violence is also common in social platforms. To give an example from the "other" side some mobs that gathered to attack Israeli Arabs during the last conflicts organized on social media. Would you be critical if those voices were suppressed?
I can be really critical of Israel for many things. But I'm really not buying that the balance is set the wrong way. Keep in mind a lot of us are consuming the kind of news that amplifies our world views anyways. Which brings me back to how do we measure this in a controlled way?
