Yes, BDS Movement acknowledges that there are many extensive boycott lists out there:

Many feel compelled to boycott any and all products and services of companies tied in any way to Israel. The proliferation of extensive “boycott lists” on social media is a result of this. The question is how to make boycotts effective and actually have an impact in holding corporations accountable for their complicity in the suffering of Palestinians?

The BDS movement uses the historically successful method of targeted boycotts inspired by the South African anti-apartheid movement, the US Civil Rights movement, the Indian anti-colonial struggle, among others worldwide.

We must strategically focus on a relatively smaller number of carefully selected companies and products for maximum impact. We need to target companies that play a clear and direct role in Israel’s crimes and where there is real potential for winning, as was the case with, among others, G4S, Veolia, Orange, Ben & Jerry’s and Pillsbury. Compelling large, complicit companies, through strategic and context-sensitive boycott and divestment campaigns, to end their complicity in Israeli apartheid and war crimes against Palestinians sends a very powerful message to hundreds of other complicit companies that “your time will come, so get out before it’s too late!”

Many of the prohibitively long lists going viral on social media do the exact opposite of this strategic and impactful approach. They include hundreds of companies, many without credible evidence of their connection to Israel’s regime of oppression against Palestinians. Many do not have clear demands to the companies as to what we expect them to do to end the boycott, making them ineffective.

If you feel like personally boycotting every company that has anything to do with Israel then go for it, but that's not a real plan.
