Desktops aren't the intended audience for x32. This stuff is for very specific scientific compute jobs that are pointer intensive (i.e., graphs etc). You won't see GNOME/KDE/whatever packages for this architecture.

The popularity of this arch won't manifest itself in general purpose software packages: most computation will be in one-off custom programs that are never released. That doesn't mean this architecture isn't popular, it just means you're using the wrong metric.

This is true- but it is also important to remember that any nonprofit that chooses this approach has to be able to demonstrate that the for-profit entity is tied into the mission and program of the organization in a substantive way- not just an unconnected business which provides revenue.The risk is running afoul of 'unrelated business income tax', and possibly cause a loss of the federal 501(c)(3) exempt status.

Anyone who thinks grants have anything more than a minimal role in nonprofit sustainability does not understand how noprofit businesses work, unless they are supported by a unit of government as an agent for the provision of human services, like Chicago Area Project which gets the bulk of its revenue from state grants.

Nonprofits generally earn the preponderance of their revenue on a continuing basis from donations by individuals and/or organizations/businesses. They work to develop large networks of interested donors by having a properly constituted board of directors- meaning that board members designated as 'money people', whose primary purpose on the board is to assist in fundraising, must meet annual donation requirements- either directly from that board member's pocket, or through the network of pockets that board member is able to access. The combination of a good set of 'money' board members, a savvy development director, events, charged services, grants, and systematic/consistently applied overhead costs all lead to sustainability. Schools and hospitals have an additional tool- they can actually earn the bulk of their revenue from investment income, which other nonprofits are not allowed to do.

That's why I modified smart-referer to send the requested URL instead of no referer at all for 3rd party URLs. That evades most checks.

It is a bromide perpetrated by ITAA and business groups that we can't find enough programmers to replace the ones who are retiring.

The simple truth is that no one wants to PAY what people are worth, and there is rampant age discrimination:

Be willing to hire, retrain, or do whatever it takes to employ people over 35 and this so-called problem will be
shown to be the chimera that it really is.

I would suggest you learn about what are known as 501(c)(12) telecommunications cooperatives. One specific example would be www.rric.net
It would also be good for you to consult the IRS information on this kind of nonprofit organization.
