Painting the situation as "corporate contributer-wannabes" and "IANAL but let's do it anyway" is loaded language that seems intended to bring up negative tropes. The first is sneering at the host of potential contributors, because the host is willing to pay the salary of the contributors. The second is not remotely backed up by the facts.
They've hired lawyers, and consulted the community. The community's predominant concern was whether the new license (Apache2) would be compatible with GPLv2.
In the "We are now in this year" link, it's explicated how they consulted a gaggle of open source lawyers, determined the predominant belief was the new license was compatible with GPLv2. But they didn't stop there – they had a lawyer draft an addendum to really ensure that!
Not a good look. Fever swamp paranoia, and wishing ill on a series of people clearly trying to do well and address every concern.
