For safety reasons
For some reason, Hasbro has gotten it into their heads that they don't want kids hurting themselves with Transformers toys, particularly kids whose parents are likely to make a big fuss about it on the news or sue over it, nor do they want to get in legal trouble for breaking laws. As a result, they put all products through clearly worthless testing in an attempt to make them safe for kids, and sometimes plan around "safety" rules or change existing toys to fit them. Both of these are filed under the collective heading of things done for safety reasons. Which is stupid. I mean, I personally only occasionally hurt myself on my toys as a kid, so that obviously means it's a non-issue, right?
Safety testing
Hasbro has several tests that come up frequently. One of the more famous ones is the "drop test," which is an evil procedure devised purely as an excuse to not release Fortress Maximus in RiD. Essentially, they don't want to release a toy that will shatter into dangerous plastic shards when you drop it onto a hard floor from more than a few feet off the ground. But that's totally wrong. If you're dumb enough to do anything with a Fortress Maximus other than let it sit on a shelf collecting dust, like play with it or transform it or be in the process of moving it onto a shelf or something, then you deserve whatever harm comes to you.
Other tests typically have similar goals, and result in Hasbro not releasing other various toys or in various changes being made to Hasbro's versions of products compared to Takara's versions. So of course only Takara cares about the fans. Sure, the Galaxy Force version of Vector Prime's wings are an accident waiting to happen, but they're painted, and paint is way more important than the physical well-being of children, right? It's not like toys are for kids or anything.
Safety standards
In addition to testing, Hasbro feels the need to make toys conform to certain rules in terms of design. Some of these are self-imposed, so obviously there must be no good reason for them because we all know better than Hasbro how toys should be designed, while others are laws mandated by national or other governments, so obviously there must be no good reason for them because governments are stupid.
The most famous case of stupid rules interfering with the toys Hasbro owes us is that of Megatron. First, in the United States, if you want to sell a toy gun, you have to put an orange cap at the end of it to annoy the fans. This is apparently to keep police officers from mistaking them for real guns and shooting stupid kids who dared to play with their toys. To make matters worse, some states have even more strict laws towards this same end, saying toy guns have to look unrealistic and be brightly colored in addition to having the stupid orange cap. Between the two of them, G1 Megatron cannot be reissued, and Classics Megatron had to be all neon and Playskool. Which is just totally wrong. After all, what's more important, the lives of some dumb kids or my hard-earned display piece?
