They are both valid and overblown rubbish.
The only way to eliminate those concerns would be to run Exchange 2010 in your own house (or preferably, data centre). Then, you have complete control over:
1. Physical security
2. Hardware monitoring & maintenance
3. Onsite and offsite backups and disaster recovery
4. Network availability and backup email spool provisioning
5. Operating system setup, configuration and security patching
6. Domain setup, configuration, and security patching
7. Operating system monitoring and security log alerting
8. Exchange 2010 configuration and availability monitoring
9. SSL certificate acquisition, renewal, deployment
10. Antispam and antivirus edge protection
11. Documentation on how to put it all back together (because NOBODY forgets to do this)
Spend a few months or years learning about all of that stuff, build it approximately 3 times over until you get it working the way you want, and pray it doesn't break while you are away on vacation.
Or, you could leave it to a company that employees hundreds or thousands of IT staff to do all of the above and generally be knowledgable and skillful in the field, and who have a vested interest in keeping the service up, stable, and secure.
So you have valid concerns, but unless you really want to become an expert in all those things, and take all the liability for handling itself, it's overblown rubbish, since there are people out there that can do it way better than you (or I), and have been doing it for a long time now.
Personally, when my current Exchange environment at home gets long in the tooth, I'll probably migrate to Microsoft's hosted Exchange (or maybe Rackspace, I dunno) - I like the idea of paying for my cloud email/calendaring/contacts, because then there are SLA's and guarantees attached to it. But either way, the big companies like MS, Google, Rackspace, etc, do a good job.
