Probably true, but it's also important that they did not lose because of the software. There are lot of great ideas that have gone in the drain because of sloppy software.
Many successful companies run the worst software you will ever seen. Yesterday there was a post about MUMPS which got me flashbacks of clients that showed me software that ran their entire 100m+ euro / year factory mostly written in MS Access / Excel on a shared drive (with the lovely locking Windows does!) mostly (this particular client had some CRM and an ERP from Dutch companies 'laying on the shelf' but 'never got around to it'). One of the biggest EU factories that creates the belts for conveyor belts runs on the worst PHP code as ERP I have ever seen. Many sites that are not Google or Facebook etc run on hacked together crap in whatever language and tech and do fine.
Twitter was crap at the start, most software in electronics was beyond unusable until recently (in some systems) etc.
You can of course lose because of sloppy software, but if your marketing is done well, I don't see why that would happen. There is an enormous overestimation how much people care about that kind of thing here on HN. From the first decade of the Windows versions to tons of Twitter outages after the launch to getting their computers hacked, passwords stolen, CCs stolen, privacy taken, slow as molasses systems, forced reboots, many crashes, bodged updates, forced updates, virus/malware scanners taking up 50%+ of your /still too expensive/ resources too much of the time, really bad iteration of the Facebook app at the moment (at least on Android), broken airplane booking forms, 404 support pages etc etc etc and yet no-one goes away because most people curse and move on to whatever. Unless your marketing is bad aka no-one uses it, it usually won't fail because of sloppy software.
