Editorial Viewpoint
Most software is a product,
not a service
Software offered “as a service” provides benefits
almost entirely to the companies producing the software and not for their customers.
I’ve complained about constant updates in this column before. Updates are a selling point of ‘software as
a service’, but they rarely fix the bugs that are plaguing us or add valuable features. New features that are
actually useful (the minority) could easily be rolled into a one-time annual
or semi-annual update.
I like having the option to decide if it is worthwhile to pay a couple of
hundred dollars for the latest version of the software based on the claimed
improvements. Why would I want to spend several times more for a “subscription” which provides very little real value?
Anti-subscription rhetoric might seem odd from a magazine publisher. But
keep in mind that you are genuinely getting something new each month when
you subscribe to a monthly magazine, unlike most software where regular
updates are just fixing things that shouldn’t have been broken in the first place.
Take CorelDraw as an example. While we use it and mostly like it, CorelDraw suffers from terrible performance at times (a problem for at least a
decade), and it’s too crash-prone for my liking. Still, it’s pretty decent overall, and we want to continue using it.
They bring out one new version a year, with perhaps a mid-year update,
but they rarely add or improve anything that makes upgrading worthwhile.
Still, when we were offered an ‘upgrade protection plan’ (UPP) for around
$130 per user per year to stay on the latest version, we accepted it.
We recently received notification that they were ending that plan, forcing
anyone who wants to use the latest version onto a $50 per month subscription
($600 per year). That’s nearly five times what we were paying. While you can
still buy the software outright, it’s $1100 per copy with no apparent upgrade
discount, making that about nine times as expensive as the upgrade plan.
Even when we were paying for separate upgrades, we were not paying $600
per year. It isn’t worthwhile, given the marginal improvements with each
version, and the lack of significant performance improvements or bug fixes.
Does Corel realise that many people like us already have Adobe Creative
Suite (including Adobe Illustrator) that we could switch to essentially for
free? We don’t want to do that, but it’s an attractive option compared to
another expensive subscription.
While I don’t like paying $70-odd per month for Creative Suite, it includes
several very useful packages, including Illustrator, Photoshop and InDesign,
making it a far better value.
Corel could have increased what they were charging us for the upgrade
service, and we would probably have continued to pay it. But now we have
cancelled all our UPPs and will stick with the 2022 version. They will get
no more money from us; good job, Corel.
It comes down to what users will tolerate. If most users say “no more” like
we did and cancel, companies will get the message. But if enough users roll
over and pay the exorbitant subscription fees, they’ll see that this scheme
works and keep it up.
This leaves the market open for a competitor to come along and offer a
reasonable alternative without the subscription fee. Any such competitor
would be guaranteed a portion of the market; those who don’t like subscription models. Also, the open-source (and free) software Inkscape is looking
more attractive by the day...
