I'm assuming they mean they're shunning Zionist scientists? I would guess that there are pro-Palestine scientists out there who have Israeli citizenship.
Edit:article is subscription-walled but from what I read it's specifically that scientists at Israeli institutions are getting dropped in protest.
This is extremely foolish. If western universities and companies shun Isreali scientist, then it won't take long for countries with antagonistic attitudes towards the west to embrace them, like Russia or China
Why would you believe this? First you would have to answer why the scientists are being shunned. Then, is this the same problem in these other countries?
Then you have to ask why would it be a bad thing for them to work elsewhere? What about the countless good scientists in the west who are unemployed? Why not be worried about them going to other countries?
I suspect you aren't involved in science at all. The default is that scientists travel between countries for opportunities. There are far more scientists than jobs for them, especially when you consider the scientists trained in very specific fields.
To be concerned with the shunning of a specific nationality of scientists ignore why they may be shunned. And to be concerned with where this specific group will then go, is low-key racist.
China? Really? The country that is delaying shipments to Isreal? The country that is currently refusing to send tech workers to Isreal? The country that has condemned what Isreal is doing? The country that Isreal claims is supplying Hamas with weapons? You think they're going to get this secret special talent from Isreal instead of American Universities? This is a real concern from you?
Congratulations, you've discovered that you're racist. And very dumb.
This partixular boycott is misaimed and pointless. Science and culture belong to the world, not to any country. By all means boycott research with military applications, or individuals who work alongside the IDF or other violent groups, but what's the point in boycotting research on medicine or water purification?
