That's easy to say, another 10,000 things to do. I don't feel abused by Pagemaker, in its day it was premier software. People didn't pay hundreds for it and then use it because they wanted abuse, it was because they wanted precise control of their printing of text and graphics intensive publications...
They didn't want the abuse. That came free of charge :^D They abuse you by locking you into their proprietary format, and this was "back in the day" when proprietary formats were one of the worst offenses. Now companies have even greater control of your computing. They tell you where, and how you can use the software, and if they don't like what you're doing, they can remotely stop you. When a company controls the data, the user doesn't.
This might sound like ideological crap that people don't need to be concerned with, but if you look at your own situation, it should be very concerning. You're facing years of work being rendered useless because the software you used is an inscrutable black box. If the code were open someone could easily write a translation program for your files. Even if you can't do it yourself, there's someone out there who has the same problem as you, but does have the skill to fix it, and with libre code, they can give, or sell the fix to you.
... and it did that marvelously and still does if their operating systems support it, and my XP machines do support it just fine AFAIK.
XP supports it NOW, but what about 10 years from now? XP may not even run on the machines of the future. That'll leave you dumpster diving antique computers to run software that should have been fixed with code, but wasn't due to the developers abuse of you when you bought the software.
I do like the open source ethic, but I'm not going to hang myself in the noose of adherence to it. I use freeware whenever possible, but I do not refuse to use for pay code. Some do, I suppose, or close to it. I try to be realistic in my decision making.
An important point... Free software doesn't have anything to do with price. That's why I prefer the term libre. Libre explicitly means freedom, and doesn't have the ambiguous English meaning of gratis as the word "free" does. You can pay a lot of money for free software, and many people do. On the other hand, you can pay nothing for non-free software as you would with Adobe Flash player, or Opera browser. If you have the 4 freedoms, you have free software(notice price is never mentioned)...
The freedom to run the program, for any purpose (freedom 0).
The freedom to study how the program works, and change it so it does your computing as you wish (freedom 1). Access to the source code is a precondition for this.
The freedom to redistribute copies so you can help your neighbor (freedom 2).
The freedom to distribute copies of your modified versions to others (freedom 3). By doing this you can give the whole community a chance to benefit from your changes. Access to the source code is a precondition for this.
Again, this might sound like philosophical bullshit, but it affects us all on a daily basis. You fell into the proprietary trap once, and Adobe now owns your data. Be careful of letting it happen again. You may not have as easy a time of fixing the issue next time.
