I would add the purpose of half of this advice is to make sure to prevent any possibility your domain possession is viewed as being used to monetise the name association with another legitimate company.
If your name is Apple and you somehow obtain new domain named apple.newtld you have a chance to loose the domain if there is any way it can be seen as profiting off of the association with the APL. For example if you put ads on a page that is nominally your personal page it can be seen as getting traffic from people who mistakenly came to this page since there is very little chance they came legitimately.
If it is large company they will be looking at every possible way to get your domain and the only way to fight it is to either spend huge amount of money on lawyers or not give any pretext, however small.
You are also as likely to lose the domain by a targeted attack by people who hope to then sell the domain. If you have a nice domain name you need to invest a bit of thought in protecting it from takover (locking the domain, protecting your information, not using your regular phone number, phone, email, laptop, etc. to have anything to do with the admin access to the domain).
