But we often hear about ‘corporate lobbying’ and you’ve described things mostly carried out by individuals or nonprofits.

No, I'm describing lobbying. The definition of lobbying doesn't depend on your market capitalization or revenue. A corporation does lobbying, just like unions do and industry representatives and community groups. If you have personal interests and want to raise awareness with stakeholders then you reach out to them.

I mean, Wikipedia's article on lobbying also refers to it as advocacy. From Wikipedia;

In politics, lobbying or advocacy, is the act of lawfully attempting to influence the actions, policies, or decisions of government officials, most often legislators or members of regulatory agencies, but also judges of the judiciary.

"Attempting to influence" is the operative principle.

And so is "lawfully". Which is not the same as the corruption you pinned on "Eastern countries".
