Anyway.. shame on you, Microsoft!!
Very little of what you ranted about is true. Yes you pay a good deal of money for licenses. But no, they are NOT "pushing updates, without any info". They are not deliberately shutting production applications. They are not forcing you to pay anything more. The update that caused this was a security update that there is no charge for. That it did cause an issue is unfortunate, but its a reflection on the complexity and interoperable of Office and Windows. A complexity and interoperability that is part of the reason for the populatiy of both software products.
There is no hidden marketing tricks here. Software gets improved, file types get improved. Microsoft tries to maintain a long term backward compatability, but can't do it forever. Other software developers don't do that.
