I now call DS my "DAZ Studio Content Exporter Utility" (DSCEU (tm) :^).

I'm not yet able to throw the good DAZ PAs out with the DAZ Inc. bathwater, but there's definitely no warm-fuzzy going on (and much less spending), and the certainty that I'll never ever mention the DAZ name or products with respect to any of my work, or to those that would ask about how to get into hobby/industry (especially the educational institutions I have cause to frequent). That endorsement/acknowledgment ship has long since sailed.

That said, re: the logistics of the DAZ store 'silo' - you can download any/all current products that you own via your web-based product library interface, and the most current DS release has always been available as both EXEs and DIM zipfiles (download and save both versions at each formal release so you can roll back to working versions, as the new versions invariably break some older unsupported or non-updated tool/script/plugin you've come to rely on...). Beta DS versions (public) only come in DIM zip format for DIM install. I don't do DAZ-Central or Connect silliness at all, so maybe you can find a way to make those 'tools' work for you.

Note that some of the standalone utilities that you might purchase at the DAZ store can only be acquired via manual download through your web product library interface. Even the DIM downloader doesn't pull over some of these. I also recommend downloading and saving the zip installers offline, as occasionally the updates don't just 'fix' problems or add improvements, but they will actually remove or reduce functions that were available in previous release zipfiles - e.g. at one point the free genesis 1 installer was released with genitals and a follow-on DIM update overwrote those installer (on user's machines) with an updated version without that 'feature'. I also found a discrepancy between my purchased products and their listing in my product library (Gn1 Ethnic Asian), where I knew I had purchased it, but it was not available in my library. I am fairly certain that this was a simple systemic error, as the bad PR that would result from DAZ 'sneaking' your products away would be far more damaging to their already souring reputation than any gain from removing Genesis1 products from user's libraries, etc. Sloppy, not evil, but it certainly makes one wonder how much 'sloppy' we're missing...

Per Wendy, the serial number management of your account is subject to questionable accuracy as well, so I always bring up that page in my web interface and 'save page as...' a PDF or 'web-page-complete' from my browser in a dated file (e.g. DAZ_Serials_20210505.pdf, etc.). You might also save the EULA at each S/N save as well since you likely won't be able to get the previous copy of the license that you actually purchased your items under after they update the license terms, unless you want to get lawyers involved - and even DAZ knows that any current EULA updates are toilet-paper relative to your older purchase agreement terms, assuming you've downloaded and saved the original installers right when you've purchased the items. They won't act as if this is the case, as why the heck would they? I wouldn't, heh.

Remember that DAZ Inc. is a company, not your friend, nor your enemy. Believing that any company would behave in anything but their own better-interest is simply foolish, regardless the so-called 'goodwill' that their marketing and product brochures would imply. BTW, Rendo is also a company and is subject to the same tensions, but to my experience, is far more pragmatic and refreshing in their behavior (except their current Poser "phone-home" requirement. sigh - never again...).
